Crystal structure of {bis[2-(3,5-dimethylpyrazol-1-yl-κN2)ethyl]amine-κN}chloridoplatinum(II) chloride dihydrate

Abstract

The title complex, [PtCl(C14H23N5)]Cl·2H2O, is isomorphous with the PdII compound characterized previously [Mendoza, Bernès & Mendoza-Díaz (2006). Acta Cryst. E62, m2934–m2936]. The angle between pyrazole mean planes in the main ligand is 88.3 (4)°, similar to that observed in the PdII analogue [87.62 (11)°]. This tridentate ligand adopts a conformation approximating a twofold symmetry, allowing its coordination to the metal atom, together with a chloride ligand, in an almost perfect square-planar geometry. A chloride anion and two water molecules in the asymmetric unit form a hydrogen-bonded network connected to the complex molecules in the crystal via the NH amine groups, forming chains along [100].
