Cl Atom

The racemic title compound, [Cu2(C7H8NO2)2Cl2], is composed of dinuclear molecules in which methoxy(pyridin-2-yl)methanolate ligands bridge two symmetry-related CuIIions. Each CuIIion is coordinated in a square-planar geometry by one Cl atom, the N and O atoms of the bidentate ligand and the bridging O atom of the centrosymmetrically related bidentate ligand. The separation between the two CuIIatoms is 3.005 (1) Å. In the crystal, non-classical C—H...O hydrogen bonds, weak π–π stacking [centroid–centroid distance = 4.073 (1) Å] and weak electrostatic Cu...Cl interactions [3.023 (1) Å] link the dinuclear molecules into chains running parallel to thebaxis. These chains are further connected by weak C—H...Cl hydrogen bonds directed approximately along theaaxis, forming a three-dimensional supramolecular network.

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.

In the title compound, [CuCl(C17H19Cl4N3)]ClO4, the CuIIion adopts a distorted square-planar geometry defined by one chloride ligand and the three nitrogen atoms from the bis[(pyridin-2-yl)methyl](3,5,5,5-tetrachloropentyl)amine ligand. The perchlorate counter-ion is disordered over three sets of sites with refined occupancies 0.0634 (17), 0.221 (16) and 0.145 (7). In addition, the hetero-scorpionate arm of the bis[(pyridin-2-yl)methyl](3,5,5,5-tetrachloropentyl)amine ligand is disordered over two sets of sites with refined occupancies 0.839 (2) and 0.161 (2). In the crystal, weak Cu...Cl interactions between symmetry-related molecules create a dimerization with a chloride occupying the apical position of the square-pyramidal geometry typical of many copper(II) chloride hetero-scorpionate complexes.
