Abstract: | The crystal and molecular structure of (trans-3,4-diamino-2,2,6,6-tetramethylpiperidine-1-oxyl-N
3, N
4)(oxalato-O,O′)platinum(II) dihydrate was studied by single crystal X-ray diffraction. The crystals belong to the monoclinic system; a 8.261, b 13.129, c 15.224 Å; β 104.29°, Z 4, space group P21/n. The structure was solved by the direct method and refined by the full-matrix least-squares method in the anisotropic approximation
to R 0.026 for all the 3660 measured unique reflections. The structure consists of individual mononuclear bischelate molecules
containing two different bidentate ligands. The Pt2+ coordination is distorted square-planar. The complex molecules and water molecules in the crystal of I are linked by hydrogen bonds forming an infinite 3D network.
