title: Crystal structures of organoplatinum complexes containing alkyl-eugenoxyacetate and p-chloro-aniline.
abstract: In the title complexes, trans-di-chlorido-(4-chloro-aniline-κN){3-meth-oxy-4-meth-oxy-carbonyl-meth-oxy-1-[(2,3-η)-prop-2-en-1-yl]benzene}-platinum(II) 0.1-hydrate, [PtCl2(C6H6ClN)(C13H16O4)]·0.1H2O, (I), and trans-di-chlorido-(4-chloro-aniline-κN){4-eth-oxy-carbonyl-meth-oxy-3-meth-oxy-1-[(2,3-η)-prop-2-en-1-yl]benzene}-platinum(II), [PtCl2(C6H6ClN)(C14H18O4)], (II), the Pt(II) metal atom displays a slightly distorted square-planar coordination geometry defined by the aniline N atom, two chloride anions (trans-positioned) and one ethyl-enic double bond. The least-squares planes through the two aromatic ring systems make an angle of 47.3 (3)° for (I) and 38.6 (2)° for (II). Both structures show disorder for the PtCl2 fragment, in the case of (I) even further extended towards the CH2-CH=CH2 ligand. An intra-molecular C-H⋯Cl hydrogen bond occurs in (I). In the crystal packing of (I), which is dominated by N-H⋯O and C-H⋯Cl inter-actions, a partially occupied water mol-ecule is observed on a twofold rotation axis with a refined site occupancy of 0.10 (1). A C-H⋯π inter-action is also present. In (II), inversion dimers form chains along the b-axis direction by N-H⋯O hydrogen bonds.
