Özet

The title compound, catena-poly[[μ-cyano-1:2k2C:N-dicyano- 1k2C-trans-bis[N-(2-hydroxyethyl)ethane-1,2-diamine-2k 2-N,N′]cadmium(II)nickel(II)]-μ-cyano-1:2k2C:N], [CdNi-(CN)4(C4H12N2O)2], consists of alternating square-planar Ni(CN)4 fragments, formally dianionic, and Cd(hydet-en)2 moieties [hydet-en is N-(2-hydroxyethyl)ethylenediamine], with the two bridging cyanide ligands in a mutually trans disposition at the Ni atom and cis at the Cd atom. The resulting one-dimensional zigzag chain structure has the Ni atom on an inversion center, while the distorted octahedron centered on the Cd atom lies on a twofold axis. The polymer chains are connected into undulating sheets by weak interchain N - H⋯N, N - H⋯O and O - H⋯N hydrogen bonds, which are also present between successive sheets.
