Abstract :
In the title complexes, trans-dichlorido(4-chloroaniline-κN){3-methoxy-4-methoxycarbonylmethoxy-1-[(2,3-η)-prop-2-en-1-yl]benzene}platinum(II) 0.1-hydrate, [PtCl2(C6H6ClN)(C13H16O4)]·0.1H2O, (I), and trans-dichlorido(4-chloroaniline-κN){4-ethoxycarbonylmethoxy-3-methoxy-1-[(2,3-η)-prop-2-en-1-yl]benzene}platinum(II), [PtCl2(C6H6ClN)(C14H18O4)], (II), the PtII metal atom displays a slightly distorted square-planar coordination geometry defined by the aniline N atom, two chloride anions (trans-positioned) and one ethylenic 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 intramolecular 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 interactions, a partially occupied water molecule is observed on a twofold rotation axis with a refined site occupancy of 0.10 (1). A C—H⋯π interaction is also present. In (II), inversion dimers form chains along the b-axis direction by N—H⋯O hydrogen bonds.
