Abstract

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 Cd^II 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.
