【 摘 要 】

In the title complexes, trans-(2-amino­pyridine-κN)di­chlorido­{4-eth­oxy­carbonyl­meth­oxy-3-meth­oxy-1-[(2,3-η)-prop-2-en-1-yl]benzene}­platinum(II), [PtCl2(C5H6N2)(C14H18O4)], (I), and (2-amino­pyridine-κN)chlorido{5-eth­oxy­car­bon­yl­meth­oxy-4-meth­oxy-1-[(2,3-η)-prop-2-en-1-yl]phenyl-κC1}­platinum(II), [Pt(C14H17O4)Cl(C5H6N2)], (II), the central PtII metal atom displays a distorted square-planar coordination, with the PtII 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.
