Abstract
- In the title complexes, trans-(2-aminopyridine-κN)dichlorido{4-ethoxycarbonyl-methoxy-3-methoxy-1-[(2,3-ŋ)-prop-2-en-1-yl]benzene}platinum(II), [PtCl<subscript>2</subscript>-(C<subscript>5</subscript>H<subscript>6</subscript>N<subscript>2</subscript>)(C<subscript>14</subscript>H<subscript>18</subscript>O<subscript>4</subscript>)], (I), and (2-aminopyridine-κN)chlorido{5-ethoxycarbonylmethoxy-4-methoxy-1-[(2,3-ŋ)-prop-2-en-1-yl]phenyl-κC¹}platinum(II), [Pt-(C<subscript>14</subscript>H<subscript>17</subscript>O<subscript>4</subscript>)Cl(C<subscript>5</subscript>H<subscript>6</subscript>N<subscript>2</subscript>)], (II), the central Pt<superscript>II</superscript> metal atom displays a distorted square-planar coordination, with the Ptn atom coordinated by the pyridine N atom, the C=C double bond of the eugenol ligand and two Cl atoms for (I) or one Cl atom and a C atom of the phenyl ring for (II). The allyl fragment in (I) is disordered, with population parameters 0.614 (14) and 0.386 (14) for the two positions of the central C atom. The least-squares planes through the two aromatic ring systems make a dihedral angle of 51.10 (13)° for (I) and 78.5 (2)° for (II). Intramolecular N -- H...O and N--H...π interactions occur in (I). In (I), inversion dimers formed by C--H...Cl interactions are further linked into chains parallel to the b axis by C--H..O hydrogen bonds. Both aromatic rings are involved in π - π interactions, with centroid-to-centroid distances of 3.508 (3) and 3.791 (3) Å. In (II), inversion dimers form chains parallel to the b axis by C--H...O interactions. [ABSTRACT FROM AUTHOR]
