catena-Poly[[silver(I)-μ-dipyrazin-2-ylamine] perchlorate monohydrate]

In the title complex, {[Ag(C8H7N5)]ClO4·H2O}n, the multidentate dipyrazin-2-ylamine acts as a μ2-bridging link with an anti–syn configuration, assembling the AgI ions into a zigzag chain structure. The AgI ion is linearly coordinated by two dipyrazin-2-ylamine ligands through two pyrazine N atoms. (ClO4 −)⋯π(pyrazine) [O⋯centroid distances of 3.612 (3) and 3.664 (1) Å] and π–π inter­actions [centroid–centroid distance = 3.518 (2) Å] as well as O—H⋯O and N—H⋯O hydrogen-bonds assemble the chains into a three-dimensional supra­molecular aggregation

Poly[hexa-μ-acetato-bis­(dimethyl sulfoxide)­trimanganese(II)]

In the title complex, [Mn3(CH3CO2)6(C2H6SO)2]n, the MnII ions exhibit similar MnO6 octa­hedral coordination geometries but with different coordination environments. One type of MnII ion is surrounded by five acetate groups and a terminal dimethyl sulfoxide group, while the other lies on a twofold axis and is coordinated by six O atoms from three symmetry-related acetate ions. The acetate anions exhibit three independent bridging modes, which flexibly bridge the MnII ions along the c-axis direction, forming an infinite chain structure; the chains are further inter­connected through weak C—H⋯O and C—H⋯S hydrogen-bonding inter­actions

2-(2,3-Dioxoindolin-1-yl)ethyl 4-(4-nitro­phen­yl)piperazine-1-carbodithio­ate

In the title compound, C21H20N4O4S2, the piperazine ring adopts a chair conformation. The 1-ethyl­indoline-2,3-dione system links to one N atom of the piperazine ring via a carbodithio­ate group. The indoline-2,3-dione ring and the nitro­benzene ring subtend adihedral angle of 37.27 (7)°. In the crystal structure, weak C—H⋯O and π–π stacking inter­actions [centroid–centroid distances = 3.534 (5) and 3.797 (5) Å] may help to establish the packing

3,3-Dichloro-1-(chloro­meth­yl)indolin-2-one

In the title compound, C9H6Cl3NO, the pyrrole ring is almost coplanar with the benzene ring [dihedral angle = 1.90 (9)°], while the Cl—C—N—C torsion angle is 98.78 (17)°. In the crystal, pairs of mol­ecules are inter­connected by pairs of Cl⋯Cl inter­actions [3.564 (5) Å], forming dimers, which are further peripherally connected through inter­molecular C—H⋯O=C and π–π inter­actions [centroid–centroid distances = 4.134 (7), 4.134 (6) and 4.238 (7) Å], forming a two-dimensional network

3,3′-Carbonyl­dipyridinium bis­(perchlorate)

In the title molecular salt, C11H10N2O2+·2ClO4 −, the complete cation is generated by crystallographic twofold symmetry. The dihedral angle between the pyridyl rings is 67.07 (7)°. The crystal structure features N—H⋯Cl hydrogen bonds, forming sheets in the ab plane

[N-Benzyl-N-(diphenyl­phosphanylmeth­yl)pyridin-2-amine]­chloridomethyl­platinum(II)

In the mononuclear title complex, [Pt(CH3)Cl(C25H23N2P)], the N-benzyl-N-(diphenyl­phosphanylmeth­yl)pyridin-2-amine functions as a bidentate ligand with the pyridyl N atom and the phosphine P atom chelating the PtII ion, forming a six-membered metallocycle. The PtII atom adopts a square-planar coordination geometry with one methyl group and one chloride ligand bonding to the metal center in a cis relationship. C—H⋯π and C—H⋯Cl inter­actions help to consolidate the packing

5-Fluoro-1-(4-meth­oxy­benz­yl)indoline-2,3-dione

In the title compound, C16H12FNO3, the dihedral angle between the benzene ring and the plane of the indole ring system is 71.60 (6)°. In the crystal, mol­ecules stack along the b axis through π–π inter­actions between the adjacent indole-2,3-dione units with a centroid–centroid distance of 3.649 (3) Å. Inter­molecular C—H⋯O=C and C—H⋯π inter­actions further stabilize the structure, forming a three-dimensional framework

Chlorido{N 2,N 6-dibenzyl-N 2,N 6-bis­[(diphenyl­phosphan­yl)meth­yl]pyridine-2,6-diamine}­methyl­platinum(II)

In the title mononuclear complex, [Pt(CH3)Cl(C45H41N3P2)], the pyridine-2,6-diamine ligand can be viewed as a centrosymmetric motif having two pendant N-benzyl-N-[(diphenyl­phosphan­yl)meth­yl] arms, the two P atoms of which chelate to the PtII ion, forming a ten-membered metallocycle. A distorted square-planar coordination geometry around the PtII atom is completed by a methyl ligand and a chloride ion. The packing between the mononuclear units is achieved through C—H⋯π inter­actions, which link the mol­ecules into chains along the c axis

[(1,2,5,6-η)-Cyclo­octa-1,5-diene]bis­(4-methyl­phen­yl)platinum(II)

In the mononuclear title complex, [Pt(C7H7)2(C8H12)], the PtII ion exhibits a square-planar coordination geometry defined by two methyl­phenyl ligands and the mid-points of the two π-coordinated double bonds of cyclo­octa-1,5-diene. The two methyl­phenyl groups have a cis relationship with a C—Pt—C bond angle of 88.54 (18)° and a dihedral angle between the mean planes of the benzene rings of 83.87 (1)°. Each complex mol­ecule links to four symmetry-related ones through inter­molecular C—H⋯π inter­actions, forming a layer almost parallel to the bc plane
