Crystal structure of2-(5-bromo-2-pyridylazo)-5-diethylaminophenolatochloropalladium(II) (PdLCl)has been determined by X-ray diffraction. A crystal of PdLCl wasconstructed by two structural isomers of PdLCl molecules, which wereparticularly different in the positions of the carbon atoms at thediethylamino group, having cis-like or trans-like conformation forthe carbon atoms. The molecules of PdLCl in the crystal were warped by asteric hindrance of the diethylamino group.
