catena-Poly[[[diaqualanthanum(III)]-tetrakis[μ-N-(4-acetamidophenylsulfonyl)glycinato]-[diaqualanthanum(III)]-bis[μ-N-(4-acetamidophenylsulfonyl)glycinato]] 4,4′-bipyridine disolvate tetradecahydrate]
In the title compound, {[La2(C10H11N2O5S)6(H2O)4]·2C10H8N2·14H2O}n, the LaIII ions are in a slightly distorted bicapped trigonal prismatic geometry, and are linked by six carboxylate groups in a syn–syn bidentate bridging fashion to form a one-dimensional inorganic–organic alternating linear chain. These polymeric chains generate microchannels extending along [100], and these cavities are occupied by discrete tetradecameric water clusters, which interact with their surroundings and finally furnish the three-dimensional supramolecular network via 15 O—H⋯O, one O—H⋯S, two O—H⋯N and six N—H⋯O classical hydrogen bonds. 4,4-Bipyridine acts as an inserting component and hydrogen-bond acceptor, and it is a nonplanar molecule with a dihedral angle of 33.12 (13)° between the pyridine rings. Owing to the numerous classical hydrogen bonds, the observed weak intermolecular C—H⋯O, C—H⋯π and π–π stacking interactions can be neglected with regard to stabilizing the network
Poly[[bis(acetonitrile-κN)bis[μ2-2,2′-(methylenedithio)bis(1,3,4-thiadiazole)-κ2 N 4:N 4′]copper(II)] bis(perchlorate) acetonitrile solvate]
In the title compound, {[Cu(C5H4N4S4)2(C2H3N)2](ClO4)2·C2H3N}n, the CuII atom occupies a crystallographic inversion centre and is six-coordinated by six N atoms of four symmetry-related 2,2′-(methylenedithio)bis(1,3,4-thiadiazole) (L) ligands and two acetonitrile molecules in a slightly distorted octahedral geometry. The ligand L adopts an N:N′-bidentate bridging mode in a trans configuration, bridging the Cu atoms via translation symmetry, forming a two-dimensional layer-like structure. The perchlorate ions serve as acceptors for intermolecular C—H⋯O hydrogen bonds, which link the layers into a three-dimensional network. The ClO4
− anion is disordered with an occupation ratio of 0.658:0.342
4-(2-Carboxybenzoyl)benzoic acid–4,4′-bipyridine (1/1)
In the heteromolecular title compound, C15H10O5·C10H8N2, the two components are linked by O—H⋯N hydrogen bonds to form four-component ring supramolecular assemblies. These are further interconnected with neighbouring molecules by weak intermolecular C—H⋯π interactions and C—H⋯O hydrogen bonds to generate a three-dimensional network
Bis(1,3,4-thiadiazol-2-yl) disulfide
The title compound, C4H2N4S4, lies about a twofold rotation axis situated at the mid-point of the central S—S bond. Each of two thiadiazole rings is essentially planar, with an rms deviation for the unique thiadiazole ring plane of 0.0019 (7) Å. C—H⋯N hydrogen bonds link adjacent molecules, forming zigzag chains along the c axis. In addition, these chains are connected by intermolecular S⋯S interactions [S⋯S = 3.5153 (11) Å] , forming corrugated sheets, and further fabricate a three-dimensional supramolecular structure by intermolecular N⋯S contacts [S⋯N = 3.1941 (17) Å]
catena-Poly[[[bis[2,2′-(propane-1,3-diyldithio)bis(1,3,4-thiadiazole)-κN 4]copper(II)]-bis[μ-2,2′-(propane-1,3-diyldithio)bis(1,3,4-thiadiazole)-κ2 N 4:N 4′]] bis(perchlorate)]
In the title compound, {[Cu(C7H8N4S4)4](ClO4)2}n, the CuII atom, occupying a crystallographic inversion centre, is six-coordinated by six N atoms of three symmetry-related 2,2′-(propane-1,3-diyldithio)bis(1,3,4-thiadiazole) (L) ligands in a slightly distorted octahedral geometry. The ligand L adopts two kinds of coordination modes in the crystal structure; one is a monodentate coordination mode and serves to complete the octahedral coordination of the Cu atom and the other is an N:N′-bidentate bridging mode in a trans configuration, bridging Cu atoms via translation symmetry along the b axis into a chain structure. The perchlorate ions serve as acceptors for intermolecular C—H⋯O hydrogen bonds, which link the chains into a three-dimensional network
Poly[[tris[μ-2,2′-(butane-1,4-diyldithio)bis(1,3,4-thiadiazole)-κ2 N 4:N 4′]copper(II)] bis(perchlorate)]
In the title compound, {[Cu(C8H10N4S4)3](ClO4)2}n, the CuII atom is located on a threefold inversion axis coordinated by six N atoms of symmetry-equivalent 2,2′-(butane-1,4-diyldithio)bis(1,3,4-thiadiazole) ligands in a slightly distorted octahedral geometry. Adjacent CuII atoms are linked by the bridging bidentate thiadiazole ligands, which are situated about inversion centers. This leads to the formation of a three-dimensional network structure
catena-Poly[[bis(nitrato-κ2 O,O′)copper(II)]-μ-2,2′-(ethane-1,2-diyldithio)di-1,3,4-thiadiazole-κ2 N 4:N 4′]
In the title compound, [Cu(NO3)2(C6H6N4S4)]n, the CuII atom, occupying a crystallographic inversion centre, is six-coordinated by two N atoms of two 2,2′-[1,2-ethanediylbis(thio)]bis[1,3,4-thiadiazole] ligands in trans positions, and four O atoms from two symmetry-related opposite nitrate anions, which are asymmetrically bonded, resulting in a strong distorted octahedral geometry of the central atom. The ethane group is equally disordered over two sites via another inversion centre. The bridging bidentate 2,2′-[1,2-ethanediylbis(thio)]bis[1,3,4-thiadiazole] ligands link the CuII centres into a one-dimensional chain. The chains are interconnected via intermolecular S⋯O interactions [3.044 (4) and 3.084 (5) Å] and weak C—H⋯O hydrogen bonds, generating a three-dimensional supramolecular structure
Di-4-pyridyl sulfide–isophthalic acid (1/1)
In the heteromolecular title structure, C10H8N2S·C8H6O4, the two components are linked by O—H⋯N hydrogen bonds to form a one-dimensional chain. These chains are further interconnected by weak intermolecular C—H⋯O hydrogen bonds and weak C—H⋯π interactions to generate a three-dimensional supramolecular structure
Di-μ-chlorido-bis{[2-(2-pyridylmethylamino)ethanesulfonato-κ3 N,N′,O]copper(II)}
In the title compound, [Cu2(C8H11N2O3S)2Cl2], the Cu atoms are five-coordinated in a distorted square-pyramidal geometry by three donor atoms of the deprotonated anionic 2-(2-pyridylmethylamino)ethanesulfonate (pmt) ligand and two Cl atoms. The Cl atoms bridge two Cu atoms, giving a binuclear structure; the centroid of the Cu2Cl2 ring lies on a crystallographic center of inversion. The complex is stabilized by hydrogen bonds and π–π stacking interactions [average interplanar distance = 3.4969 (1) Å and ring-centroid separation distance = 4.1068 (4) Å]

In the title compound, [AgCl(C2H2N2S2)]n, the AgI ion has a distorted tetrahedral geometry, defined by two S atoms of two symmetry-related 1,3,4-thiadiazolium-2-thiolate ligands and two chloride ions. The AgI ions are bridged into a two-dimensional network parallel to the ab plane by chloride ions and thiadiazole ligands. In the network, the AgI ions are separated by 4.0316 (12) Å along the a axis and by 4.8822 (13) Å along the b axis. N—H⋯Cl hydrogen bonds are observed within the network
