The hydrated title salt, CdCl(CHN)·0.81HO, 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 2/, with the other components in general positions. The cation has approximate, but non-crystallographic 2/ symmetry and each of the Cd atoms is a stereogenic centre, one having the Δ configuration and the other the Λ configuration. In the anion, one of the C(CN) 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 (14) and (24) rings.
水合标题盐CdCl(CHN)·0.81HO是通过2,2'-联吡啶、氯化镉(II)和1,1,3,3-四氰基-2-乙氧基丙烯酸钾之间的水热反应得到的。双核阳离子位于空间群2/的对称中心上，其他组分处于一般位置。该阳离子具有近似但非晶体学的2/对称性，并且每个镉原子都是一个手性中心，一个具有Δ构型，另一个具有Λ构型。在阴离子中，一个C(CN)单元在两组原子位置上无序，占有率分别为0.75(2)和0.25(2)。阳离子通过两个独立的C-H⋯Cl氢键相连，形成由(14)和(24)环组成的片层。
