摘要：

Solid-state structures of trans-[RuCl2 ( Cl2PN(Me)N(Me)PCl2}(2)] (1), cis-[PdCl2 {Cl2PN(Me)N(Me)PCl2}] (2), and cis-[PtCl2{Cl2PN(Me)N(Me)PCl2}] (3) were studied by using (13)CCPMAS NMR spectroscopy and X-ray crystallography. The ruthenium atom in 1 was on a crystallographic inversion center and had a slightly distorted octahedral coordination. 2 and 3 contained palladium and platinum atoms in a square-planar geometry, respectively. In 2, axial sites of the Pd atom were filled by intermolecular Pd Cl contacts to form an infinite chain. Molecules of 3 pack in an edge-toface manner and no obvious "axial" contacts at the Pt atom were observed. Different geometries of hydrazide nitrogens in 1, 2, and 3 were observed: in 1 and 2, one of the nitrogen atoms was trigonal planar and the other one was pyramidal; the two hydrazine nitrogen atoms in 3 had trigonal planar geometry. (13)CCPMAS NMR spectra are consistent with X-ray data. The P-N distances are shorter than normally accepted P-N single bond lengths, suggesting a degree of P-N pi bonding.
