Methyl, hydrochalcogenido, and phenylchalcogenolate complexes of zinc in a sulfur rich coordination environment: syntheses and structural characterization of the tris(2-mercapto-1-tert-butylimidazolyl)hydroboratozinc complexes [TmBut]ZnMe, [TmBut]ZnEH (E = S, Se) and [TmBut]ZnEPh (E = O, S, Se, Te)

Abstract

A series of hydrochalcogenido and phenylchalcogenolate complexes of zinc supported by tris(2-mercapto-1-tert-butylimidazolyl)hydroborato ligation, [Tm^But]ZnEH (E = S, Se) and [Tm^But]ZnEPh (E = O, S, Se, Te) have been synthesized from [Tm^But]ZnMe; structural characterization by X–ray diffraction indicates that the variation in Zn–E bonding as a function of the chalcogen is significantly different from that in other series of metal–chalcogenolate compounds.
