Preparation, crystal structure and attempts to cyclometallate tans-bis(D-camphor oxime-N)dichloropalladium(II)

The title complex was prepared and shown to be resistant towards cyclometallation, as were the corresponding dibromo- and di-iodo-complexes. Crystals of the title compound are orthorhombic, space group P212121, with a= 1 263.1(3), b= 2 610.5(10), c= 685.3(2) pm, and Z= 4. The molecule has approximate C2 symmetry, with both camphoryl groups to the same side of the co-ordination plane, while the two oxime O–H groups on the other side engage in an unusual hydrogen-bond chelate system with a chlorine atom of a neighbouring molecule.
