摘要：

N,N',N "-tri(isopropyl)guanidinate complexes of M(v) (M = Nb, Ta) bearing imido ligands represent unique examples of monoanionic and dianionic guanidinate complexes of these metals; single crystal X-ray analyses for two of the latter species, {[mu-(NPri)(3)C](2)TaMe(NPri)}(Mg2Cl2). 4C(6)D(6) and {(mu-eta(2):eta(2) ((PrN)-N-i)(3)C)Ta(NPri)Cl}(2), exhibit unusual bonding modes involving all of the nitrogen centers of the ligand.
