Sodium bis(ethylenediamine)copper(II) tetracyanidocuprate(I)

P. W. R. Corfield, R. K. Dobbs and B. Bell

Abstract: The title compound, Na[Cu(en)2][Cu(CN)4], where en represents ethylenediamine, NH2CH2CH2NH2, crystallizes as a salt with two distinct cations, Na+ and [CuIIen2]2+, and discrete [CuI(CN)4]3- anions. The anion geometry is tetrahedral, with angles at the copper atom ranging from 105.0 (1) to 115.4 (1)°. The Cu-C distances are in the range 1.976 (3) to 1.993 (3) Å. The divalent copper atom is coordinated by four N atoms of the two bidentate en ligands in a slightly distorted square-planar geometry. In the crystal, each sodium ion interacts with cyanide N atoms of four different anions, with Na-N distances lying in the narrow range of 2.344 (3) to 2.367 (3) Å, and an approximately tetrahedral arrangement around the sodium ions. The interacting sodium ions and [CuI(CN)4]3- anions form a three-dimensional network with channels which contain the [Cu(en)2]2+ cations. One of the chelate rings in the cation shows partial disorder between two different conformations and the C atoms were refined with occupancies in the ratio 0.817 (15):0.183 (15).
