Crystal structure of meso-di-?-chlorido-bis-[bis-(2,2'-bi-pyridine)-cadmium] bis-(1,1,3,3-tetra-cyano-2-ethoxy-propenide) 0.81-hydrate.

ABSTRACT: The hydrated title salt, [Cd2Cl2(C10H8N2)4](C9H5N4O)2·0.81H2O, was obtained from the hydro-thermal reaction between 2,2'-bi-pyridine, cadmium(II) chloride and potassium 1,1,3,3-tetra-cyano-2-eth-oxy-propenide. The binuclear cation lies across a centre of inversion in the space group P21/c, with the other components in general positions. The cation has approximate, but non-crystallographic 2/m symmetry and each of the CdII atoms is a stereogenic centre, one having the ? configuration and the other the ? configuration. In the anion, one of the C(CN)2 units is disordered over two sets of atomic sites having occupancies 0.75?(2) and 0.25?(2). The cations are linked by two independent C-H?Cl hydrogen bonds to form a sheet of R22(14) and R42(24) rings.
