Crystal structure of it meso-di-µ-chlorido-bis[bis(2,2′-bipyridine)cadmium] bis(1,1,3,3-tetracyano-2-ethoxypropenide) 0.81-hydrate
MetadataShow full item record
The hydrated title salt, [Cd2Cl2(C10H8N2)4](C9H5N4O)2·0.81H2O, was obtained from the hydrothermal reaction between 2,2′-bipyridine, cadmium(II) chloride and potassium 1,1,3,3-tetracyano-2-ethoxypropenide. The binuclear cation lies across a centre of inversion in the space group it 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 Δ configuration and the other the Λ 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 it R22(14) and it R42(24) rings.
