Tris(ethane-1,2-diamine-²N,N')cobalt(II) cis-aqua-2O--cyanido-1:2²C:N-heptacyanido-1⁷C-bis(ethane-1,2-diamine-2²N,N')cobalt(II)molybdenum(IV) dihydrate

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