The title compound, [PtCl2(C26H22P2)]·2CHCl3 (I), is the third monoclinic polymorph of this platinum(II) complex involving the bidentate ligand cis-1,2-bis(diphenylphosphanyl)ethylene (cis-dppe) [for the others, see: Oberhauser et al. (1998a). Inorg. Chim. Acta, 274, 143–154, and Oberhauser et al. (1995). Inorg. Chim. Acta, 238, 35–43]. The structure of compound (I) was solved in the space group P21/c, with one complex molecule in the asymmetric unit along with two solvate chloroform molecules. The PtII atom is ligated by two P and two Cl atoms in the equatorial plane and has a perfect square-planar coordination sphere. In the crystal, the complex molecule is linked to the chloroform solvate molecules by C—H...Cl hydrogen bonds and face-on C—Cl...π interactions. There are also weak offset π–π interactions present [intercentroid distances are 3.770 (6) and 4.096 (6) Å], linking the molecules to form supramolecular sheets that lie in the bc plane.

The title compound, [Au(C18H10F4PS)Cl2], crystallizes as neutral molecules, with the AuIIIatom coordinated by two Cl atoms and by the P and S atoms of the bidentate phosphanyl thiolate ligand, in a slightly distorted square-planar environment. The molecules are linked into centrosymmetric dimersvialong axial Au—Cl bonds of 3.393 (4) Å. This axial Au—Cl distance is longer than is usually seen, although one other example has been given. Dimer formation may explain the unexpectedly low solubility of the compound in common polar solvents. There is also a separate intermolecular Au—F contact of 3.561 (6) Å, but this distance seems too long to be regarded as a bond. Two putative C—H...F hydrogen bonds appear to link the dimers into sheets parallel to (110). There is a short intermolecular F...F contact of 2.695 (10) Å between two dimers related by the twofold axis.

The asymmetric unit of the title compound, 3C10H8N2·2C7H7NO2, consists of three molecules of 4,4′-bipyridine (bpy) and two molecules of 3-aminobenzoic acid (bza). Two molecules of bza and two molecules of bpy are connectedviaO—H...N, N—H...N and N—H...O hydrogen bonds, forming forming infinite double-stranded zigzag chains along thecaxis. The third molecule of bpy is linked to the chain by weak C—H...O interactions. Adjacent chains are linked via π–π interactions [centroid–centroid distances = 3.759 (3)–3.928 (3) Å] involving the pyridine rings of bpy molecules, resulting in a sheet-like structure parallel to (100). These sheets are stackedviaC—H...π interactions, resulting finally in the formation of a three-dimensional supramolecular structure.
