title: (6,7-Dimethyl-2,3-di-2-pyridylquinoxaline)bis(3-methylpyridine)platinum(II) bis(hexafluorophosphate) acetone solvate 0.5-hydrate.
abstract: The crystal structure of the title compound, [Pt(C6H7N)2(C20H16N4)](PF6)2.C3H6O.0.5H2O, is composed of a bivalent square-planar platinum(II) complex, two PF6- counter-ions and solvent molecules. The di-2-pyridylquinoxaline ligands are known to confer an 'L shape' on square-planar platinum(II) complexes, which also display intercalating properties. The structural characterization reported here is a contribution to a wide-ranging study focused on structural and dynamical analyses of these substrates, which may provide better insight into their biological mechanisms and activities. The expected 'L-shaped' skeleton of the metallic complex combined with the antiparallel orientation of substituted pyridines (anti conformation) generates chiral objects, found in the solid state as a racemic mixture.
