Monodentate Ligation of Tetracyanonickelate(II): (2-Aminoethanol)[N-(2-aminoethyl)-1,2-ethanediamine][tetracyanonickelato(II)]copper(II)-Water (1/2)

In the title complex, [CuNi(CN)₄(C₄H₁₃N₃)(C₂H₇NO)].2H₂O, the Cu, chelated with a terdentate dien [dien = N-(2-aminoethyl)-1,2-ethanediamine] and a bidentate mea (mea = 2-aminoethanol) ligand, is ligated additionally with [Ni(CN)₄]^2- monodentately at the N atom of one CN group; the three other N atoms are free from ligation. The monodentate ligation is a rare example of tetracyanonickelate(II) bridging to another coordination centre through only one CN group.
