Crystal structures of organoplatinum complexes containing alkyleugenoxyacetate and p -chloroaniline

In the title complexes, trans -dichlorido(4-chloroaniline-κ N ){3-methoxy-4-methoxycarbonylmethoxy-1-[(2,3-η)-prop-2-en-1-yl]benzene}platinum(II) 0.1-hydrate, [PtCl 2 (C 6 H 6 ClN)(C 13 H 16 O 4 )]·0.1H 2 O, (I), and trans -dichlorido(4-chloroaniline-κ N ){4-ethoxycarbonylmethoxy-3-methoxy-1-[(2,3-η)-prop-2-en-1-yl]benzene}platinum(II), [PtCl 2 (C 6 H 6 ClN)(C 14 H 18 O 4 )], (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 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 PtCl 2 fragment, in the case of (I) even further extended towards the CH 2 —CH=CH 2 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.
