Three　palladium　(II)　complexes　with　the　isonitrosobenzoylacetoneimine　(HIBI)　ligand,　Pd　(p-CH3C6H4IBI)2　(1),　Pd(C6H5IBI)2　(2)　and　Pd2Cl　2　(C6H5CH2IBI)2　·　CHCl3　(3),　were　prepared　and　characterized　by　IR,　Raman　and　X-ray　diffraction　studies.　The　geometries　around　the　palladium　atoms　in　the　complexes　1　and　2　are　distorted　trans-PdN4　square　planes,　and　the　Schiff　base　ligands　RIBI-　are　coordinated　through　their　oximo-nitrogen　atoms　and　imino-nitrogen　atoms.　The　week　Pd　⋯　H-C　agostic　interactions　[Pd　⋯　H　=　0.2764　nm]　complete　the　hexacoordinate　environment　around　palladium　in　the　complex　1.　The　octahedral　deformation　of　the　classical　square　planar　environment　of　the　Pd　atom　is　due　to　the　week　Pd⋯O(1b)　interactions　[Pd-O(1b)=　0.3157(9)　nm]　in　the　complex　2.　The　complex　3　is　a　first　example　of　binuclear　complex　with　isonitrosoketoimine　ligands,　in　which　one　of　oximo　groups　is　coordinated　through　oximo-nitrogen　and　oximo-oxygen　atoms.
