metal-organic compounds
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.
