Ureato(1−) complexes of palladium(II) and platinum(II)
摘要:
The reaction of [NBu4](2)[{M(C6F5)(2)(mu-OH)}(2)] (M=Pd, Pt) with amines R2NH in the presence of the heterocumulene phenylisocyanate, PhNCO, leads to the synthesis of the ureato(1-) complexes [NBu4][M(C6F5)(2){PhNC(O)NR2}] (M = Pd, Pt). The single-crystal structure of [NBu4][(C6F5)(2)Pt{PhNC(O)NPr2i}] revealed the presence of a N,N'-chelating ureato(1-) with a 2 N(1)-Pt-N(2) bite angle of 64.0(3)degrees. (C) 2003 Elsevier B.V.
