cis-Diamminedichloridoplatinum(II) N,N-dimethyl-formamide monosolvate.

In the title compound, cis-[PtCl2(NH3)2]·C3H7NO, the metal complex mol-ecules are stacked parallel to the b axis, forming close Pt⋯Pt inter-actions of 3.4071 (7) and 3.5534 (8) Šand weak N-H⋯Cl hydrogen bonds between the ammine ligand and the Cl atoms of the neighboring complex. Conventional N-H⋯O hydrogen bonds are formed between ammine ligands and the O atom of adjacent N,N-dimethyl-formamide mol-ecules. The crystal was found to be a split crystal and was analyzed using two domains related by a rotation of ca 4.4° about the reciprocal axis (-0.351 1.000 0.742) and refined to give a minor component fraction of 0.084 (6).
