    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

    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

    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

    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]

    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

    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

    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

    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
