Synthesis and structure of [{Sb(NCy)3}{Cd[N(SiMe3)2]}3]· [Li{N(SiMe3)2}·thf]2, containing a bimetallic [SbCd3] cage

The reaction of [{Sb(NCy)3}2Li6] with [Cd{N(SiMe3)2}2] (1∶6 equivalents) gave the unusual co-complex [{Sb(NCy)3}{Cd[N(SiMe3)2]}3]·[Li{N(SiMe3)2}·thf]2, containing a heterobimetallic [SbCd3] cage.
