Abstract: Bis(1-methyl-3(o-tolyl)triazene-1-oxido)palladium(II) (PdL2), has been synthesized from Na2PdCl4 and HL and chromatographically separated into trans and cis forms which have been structurally characterized. The trans isomer is centrosymmetric. The chelate rings are excellently planar in both isomers. The pendent aromatic rings in the cis isomer make a dihedral angle of only 15.6° suggesting the presence of some π π interaction between them. Upon melting the cis isomer it is spontaneously converted to the trans form.
