b Laboratory Center, Fuzhou University, Fuzhou, Fujian 350002, China Three palladium(II) complexes with the isonitrosobenzoylacetoneimine (HIBI) ligand, Pd( p CH 3C 6H 4IBI) 2(1), Pd(C 6H 5IBI) 2(2) and Pd 2Cl 2(C 6H 5CH 2IBI) 2·CHCl 3(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 PdN 4 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.
