摘要:
The title compound, [PdCl2(C20H16N4)].H2O, contains the first example of 6,7-dimethyl-2,3-bis(2-pyridyl)quinoxaline chelating a square-planar-coordinated metal via its pyridine N atoms. In the solid state, pairs of centrosymmetrically-related molecules form a 'head-to-tail' arrangement, with a significant graphitic interaction between the parallel aromatic rings. The layers formed by these pairs are interconnected by Cl...H-C bonds. Molecules of water of crystallization are interposed between these layers.
