cis-bis(dimethyl sulfide)dinitratoplatinum(II) at 295 and 150 K

The title compound, [Pt(NO(3))(2)(C(2)H(6)S)(2)], crystallizes in the P2(1)/n space group (Z' = 2), with pseudo-square-planar coordination geometry. The complex forms dimers with pseudosymmetry C(i) arranged in columns along the b-axis direction, with Pt...Pt distances of 6.3056 (3) and 4.2382 (2) A (at 150 K). Each column is surrounded by six other columns in a honeycomb rod-like packing. The coordination mode of the nitrate ligands is monodentate, with Pt-O-N angles ranging from approximately 117 to approximately 118 degrees and a tilt between the nitrate ligands and the coordination planes in the range approximately 63-70 degrees (at 150 K). The coordination mode of the nitrate ligands is compared with that observed in reported Pt(NO(3))(2)L(2) complexes (where L is a ligand with a donor atom from group 15 or 16), all of which are monodentate, with an average Pt-O-N angle of 118 (2) degrees and a tilt in the range 90 +/- 30 degrees (with two exceptions, in which the nitrates are approximately in the coordination plane).
