Ureato(1−) complexes of palladium(II) and platinum(II): Crystal structure of [NBu4][(C6F5)2Pt{PhNC(O)NPri 2}]

The reaction of [NBu4]2[{M(C6F5)2(μ-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)2Pt{PhNC(O)NPri 2}] revealed the presence of a N,N′-chelating ureato(1−) with a N(1)PtN(2) bite angle of 64.0(3)°.
