Abstract
In the title complexes, <i>trans</i>-(2-amino-pyridine-κ<i>N</i>)di-chlorido-{4-eth-oxy-carbonyl-meth-oxy-3-meth-oxy-1-[(2,3-η)-prop-2-en-1-yl]benzene}-platinum(II), [PtCl<sub>2</sub>(C<sub>5</sub>H<sub>6</sub>N<sub>2</sub>)(C<sub>14</sub>H<sub>18</sub>O<sub>4</sub>)], (I), and (2-amino-pyridine-κ<i>N</i>)chlorido{5-eth-oxy-car-bon-yl-meth-oxy-4-meth-oxy-1-[(2,3-η)-prop-2-en-1-yl]phenyl-κ<i>C</i><sup>1</sup>}-platinum(II), [Pt(C<sub>14</sub>H<sub>17</sub>O<sub>4</sub>)Cl(C<sub>5</sub>H<sub>6</sub>N<sub>2</sub>)], (II), the central Pt<sup>II</sup> metal atom displays a distorted square-planar coordination, with the Pt<sup>II</sup> 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). Intra-molecular N-H⋯O and N-H⋯π inter-actions occur in (I). In (I), inversion dimers formed by C-H⋯Cl inter-actions are further linked into chains parallel to the <i>b</i> axis by C-H⋯O hydrogen bonds. Both aromatic rings are involved in π-π inter-actions, with centroid-to-centroid distances of 3.508 (3) and 3.791 (3) Å. In (II), inversion dimers form chains parallel to the <i>b</i> axis by C-H⋯O inter-actions.
