cis-Tetra­chloridobis(1H-imidazole-κN 3)platinum(IV)

In the title complex, cis-[PtCl4(C3H4N2)2], the PtIV ion lies on a twofold rotation axis and is coordinated in a slightly distorted octa­hedral geometry. The dihedral angle between the imidazole rings is 69.9 (2)°. In the crystal, mol­ecules are linked by N—H⋯Cl hydrogen bonds, forming a three-dimensional network

trans-Tetra­chloridobis(diphenyl­aceto­nitrile)platinum(IV)

In the title compound, [PtCl4(C14H11N)2], the Pt atom lies on an inversion center and has a distorted octa­hedral environment. The main geometric parameters are Pt—N = 1.960 (5) Å, and Pt—Cl = 2.3177 (12) and 2.3196 (12) Å. The N C bond is a typical triple bond [1.137 (7) Å]. The Pt—N C—C unit is almost linear, with Pt—N—C and N—C—C angles of 174.6 (4) and 177.1 (6)°, respectively

2-[(Pyridin-2-yl)amino]pyridinium 2,4,6-trinitrophenolate

In the cation of the title salt, C10H10N3+·C6H2N3O7−, the pyridine and pyridinium rings are linked by an intramolecular N—H...N hydrogen bond and are approximately coplanar, with a dihedral angle between their planes of 4.24 (6)°. In the crystal, the cations and anions are linked through N—H...O hydrogen bonds, forming supramolecular chains propagating along the c-axis direction. π–π stacking is observed between neighbouring chains, the centroid–centroid distances being 3.7638 (11) (between pyridinium rings) and 3.5331 (11) Å (between benzene rings)

Dichloridobis[3-(4-chlorophenyl)-2,N,N-trimethyl-2,3-dihydro-1,2,4-oxadiazole-5-amine-κN4]platinum(II)–4-chlorobenzaldehyde (1/1)

In the title 1:1 co-crystal, [PtCl2(C11H14ClN3O)2]·C7H5ClO, the coordination polyhedron of the PtII atom is slightly distorted square-planar with the chloride and 2,3-dihydro-1,2,4-oxadiazole ligands mutually trans, as the Pt atom lies on an inversion center. The 4-chlorobenzaldehyde molecules are statistically disordered about an inversion centre with equal occupancies for the two positions. The PtII complex forms a three-dimensional structure through C—H...Cl and weaker C—H...O interactions with the 4-chlorobenzaldehyde molecule

Tetrakis[bis(pyridin-2-yl)amine-κN2](nitrato-κO)silver(I)

In the title complex, [Ag(NO3)(C10H9N3)4], the nitrate ligand is found to be disordered over two sets of positions, with occupancy factors of 0.473 (5) and 0.527 (5). The AgI ion is located in a square-pyramidal coordination environment formed by four N atoms from four bis(pyridin-2-yl)amine ligands and one O atom from a nitrate ligand. Weak interactions between the AgI ions and the nitrate anions acting in a monodentate mode [Ag...O = 2.791 (13) and 2.816 (9) Å for the major component of the nitrate ligand, and 2.865 (8) and 2.837 (8) Å for the minor component] link the complex molecules into a chain along [001]. N—H...O hydrogen bonds are observed

trans-Dichloridobis(3,4-dimethylpyridine)platinum(II)

In the title compound, trans-[PtCl2(C7H9N)2], the PtII atom is located on an inversion center and is coordinated by two 3,4-dimethylpyridine ligands and two chloride ligands, resulting in a typical slightly distorted square-planar geometry. The crystallographic inversion centre forces the value of the C—N—N—C torsion angle to be linear and the 3,4-dimethyl-pyridine ligands to be coplanar
