摘要：

The title complex, [Zn(C15H22BN6)(C2H3O2)] or (Tp(Me,Me))Zn(OAc), contains a tripodal tris(pyrazolyl)hydroborate ligand, a monodentate acetate ligand and a Zn-II centre in a distorted tetrahedral coordination environment capped on one triangular face by a secondary Zn center dot center dot center dot O interaction with the second O atom of the acetate ligand. The four-coordination of Zn-II and the essentially monodentate character of the acetate ligand are due to the high steric demands of the ligand set, which prevent chelate formation and five-coordination and lead to relatively long Zn-O and Zn-N bonds compared with related complexes of Zn-II and other metals.
