Synthesis and structure of novel coordination compounds based on [Re 6Q8(CN)6]4- (Q = S, Se) and (SnMe3)+

Abstract

The reactions of SnMe3Cl with salts of the cluster anionic complexes [Re6Q8(CN)6]4- (Q = S, Se) gave novel complexes [{(SnMe3)2(OH)} 2{SnMe3}2{Re6S8(CN) 6}] (I), (Me4N)2[{SnMe3(H 2O)}2{Re6Se8(CN)6}] (II), [{(SnMe2)4(μ3-O)}2{Re 6Se8(CN)6}] (III), and [(SnMe2) 4(μ3-O)2(μ2-OH) 2(H2O)2][{SnMe3 2{Re 6Se8(CN)6}] (IV). The structures of I-IV were determined by X-ray diffraction. Compounds I, IV have the chain structures with the CN-SnMe3-NC bridges between the cluster anions [Re 6Q8(CN)6]4-. Compound II contains isolated fragments {SnMe3(H2O)}2{Re 6Se8(CN)6}2-. In the polymer framework of compound III, the cluster anionic complexes [Re6Se 8(CN)6]4- are bound by the complex cations [(SnMe2)4(μ3-O)2]4+ formed due to the hydrolysis of the initial (SnMe3)Cl. © 2007 Pleiades Publishing, Ltd.
