Tris(ethane-1,2-diamine-κ2N,N′)cobalt(II) cis-aqua-2κO-μ-cyanido-1:2κ2C:N-heptacyanido-1κ7C-bis(ethane-1,2-diamine-2κ2N,N′)cobalt(II)molybdenum(IV) dihydrate

Abstract

The title compound, [Co(C2H8N2)3][CoMo(CN)8(C2H8N2)2(H2O)]·2H2O, is isostructural with the NiII analogue. The MoIV atom is coordinated by eight cyanide ligands, one of which forms a bridge to a CoII atom that is itself coordinated by two bidentate ethane-1,2-diamine (en) ligands and one water molecule. Another CoII complex, coordinated to three bidentate en ligands, acts as the counter-ion. The crystal structure contains O—H...N/O, N—H...N/O and C—H...N/O hydrogen bonds, which form a three-dimensional network.
