Preparation and characterisation of mononuclear Pd(II) complexes with 1,8-bis(3,5-dimethyl-1-pyrazolyl)-3,6-dithiaoctane (bddo) ligand: Spectroscopy studies and crystal structure of trans-[Pd(SCN)2(bddo)]

The reaction of trans-[PdCl2(bddo)] with cyanide, thiocyanate or azide produces the complexes [PdX2(bddo)]. However, the reaction with pyridine yields a mixture of [Pd(bddo)(py)2](BF4)2 (78%) and [Pd(bddo)](BF4)2 (22%) complexes, and the reaction with triphenylphosphine only affords [Pd(bddo)](BF4)2.
