Abstract
Counter-diffusion of the aqueous solution of Cs2.75K1.25[Re6Se8(CN)4(OH)2] and a water-ammonia solution of NiCl2 afforded crystals of a rhenium cluster complex trans-{[Ni(NH3)5]2[Re6Se8(CN)4(OH)2]}·6H2O. The structure of the complex is determined by single crystal X-ray diffraction. In the structure, nickel atoms have an octahedral coordination environment involving nitrogen atoms of five NH3 ligands and one CN ligand of the cluster anion. The anion has two bridging CN ligands in the trans-positions.
