Synthesis and structure of [Sn(mit)6Cu4]; a [SnCu4] cage supported by Sn–Cu cluster bonding [mit = (CH)2N(Me)C(S)N]
Abstract
The reaction of [Sn(mit)2]n with CuCl gives the heterobimetallic complex [{Sn(mit)6Cu4] 1, in which the hypho-hexagonal-bipyramidal [SnCu4] core is stabilised by SnII–CuI cluster bonding between the endo lone pair of the Sn centre and the tetrahedral Cu4 fragment.
