Abstract

Two isostructural compounds of the composition [M(NH 3 ) 6 ] 4 [{M(NH 3 ) 2 }{Re 3 Mo 3 Se 8 (CN) 6 } 2 ]·15H 2 O (M = Co, Ni) are obtained by a reaction of a salt of heterometal cluster [Re 3 Mo 3 Se 8 (CN) 6 ] 5− anion with cobalt or nickel salts in an aqueous ammonia solution. The obtained compounds are structurally characterized. They correspond to the class of cyano-bridged coordination polymers. Two cyano groups of the octahedral cluster in the trans position form bridging bonds with Co(II) and Ni(II) cations. The obtained compounds are composed of highly charged polymeric [{M(NH 3 ) 2 }{Re 3 Mo 3 Se 8 (CN) 6 }2] ∞∞ 8− 88 layers formed by cluster anions and metal cations. The negative charge of the layers is compensated by [M(NH 3 ) 6 ] 2+ cationic complexes inside the polymeric layer and in the interstitial space of the structure.
