N2 - 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 P21/c (monoclinic), a=11.272(5), b=14.034(7), c=10.163(5) Å, β=116.13(3)°, 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 PtN and PtO distances average 2.038 and 2.013 Å, 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.
