摘要：

The crystal structure of the trans-dl-1,2-diaminocyclohexane(N-methyliminodiacetato)platinum(II) complex has been determined by X-ray diffraction. It has the following parameters: space group P2(1)/c (monoclinic), a = 11.272(5), b = 14.034(7), c = 10.163(5) angstrom, beta = 116.13(3)-degrees, Z = 4. The slightly distorted square plane of the Pt includes two nitrogens of the diamine in cis positions and one oxygen and one nitrogen from N-methyliminodiacetate ion. The Pt-N and Pt-O distances average 2.038 and 2.013 angstrom, respectively. An intricate system of hydrogen bonds which involves every hydrogen atom not attached to carbon was observed. The molecule is a zwitterion and the charge density on the unbound carboxylate is probably stabilized through this series of strong hydrogen bonds.
