cis-Pt(NH3)(cyclopentylamine)Cl2.1/4H2O, C5H14Cl2N2Pt.0.25H2O, Mr = 372.7, tetragonal, P-4b2, a = 11.456 (4), c = 16.172 (6) A, V = 2122 (1) A3, Z = 8, Dx = 2.333 Mg m-3, lambda(Mo K alpha) = 0.71069 A, mu = 13.83 mm-1, F(000) = 1380, T = 295 K, R = 0.040 for 725 unique observed reflections. Pt has cis square-planar coordination with bond distances Pt-Cl = 2.31 (1), 2.33 (1) A and Pt-N = 2.02 (3) and 1.99 (2) A. The C atoms in the cyclopentylamine ligand, especially C(4), show very high thermal motion. The structure is stabilized by hydrogen bonding involving the ammine ligand and the amino group with the chloro ligands. K[Pt(cyclopentylamine)Cl3].1/2H2O, K+.C5H11Cl3NPt-.0.5H2O, Mr = 434.7, monoclinic, C2/c, a = 33.169 (21), b = 5.881 (4), c = 12.280 (8) A, beta = 102.45 (5) degrees, Z = 8, V = 2339 (3) A3, Dx = 2.468 Mg m3, lambda(Mo K alpha) = 0.71069 A, mu = 13.13 mm-1, F(000) = 1608, T = 295 K, R = 0.043 for 1399 unique observed reflections. Pt has square-planar coordination with Pt-Cl = 2.313 (4), 2.309 (4), 2.304 (4) A, and Pt-N = 2.03 (1) A. The carbon atoms of cyclopentylamine are disordered and two positions were refined for C(1). The compound crystallizes with a molecule of water located on a twofold axis. The water molecule is exceptionally close to the K+ ion [O...K = 2.756 (9) A]. The compound is stabilized by hydrogen bonds between the amino group and one chloro ligand.
