Novel palladium(Ⅱ) complexes of the type Pd(IBA-NH)(IBA-NH') and Pd(IBA-NR)2, where IBA-NH and IBA-NR (R: methyl, ethyl, n-propyl, n-butyl, benzyl) represent isonitrosobenzoylacetone imine and its N-alkyl derivatives respectively, have been prepared. The ir, nmr, and electronic spectra of the palladium(Ⅱ) complexes have been studied. It has been determined that the isonitroso group of IBA-NH coordinates to palladium through the oxygen to form 6-membered chelate ring and that of IBA-NH' coordinates to palladium through the nitrogen to form 5-membered ring in square-planar Pd(IBA-NH)(IBA-NH') and it also has been determined that the isonitroso groups of two IBA-NR coordinates to palladium through the nitrogen to form 5-membered rings in square-planar Pd(IBA-NR)2. The coordination manner of the ligands is similar to that of isonitrosoacetylacetone imines obtained by Bose, et al.
