Synthesis and Structural Characterization of Palladium(II) Mixed-Ligand Complexes of -(Benzothiazol-2-yl)benzamide and 1,2-Bis(diphenylphosphino)ethane.

Three novel palladium(II) mixed-ligand complexes of -(benzothiazol-2-yl)benzamide (HL) and 1,2-bis(diphenylphosphino)ethane (dppe), [Pd(HL)(dppe)]Cl (), [Pd(L)(dppe)]Cl (), and [Pd(L)(dppe)] (), were synthesized and fully characterized using Fourier transform infrared, H, C, and P NMR, and molar conductivity measurements. Complex was characterized by single-crystal X-ray diffraction. The ligand HL showed three different coordination modes: a neutral bidentate chelate bound through the endocyclic nitrogen and exocyclic oxygen atoms in , a negatively charged L bound as a bidentate chelate through the endocyclic nitrogen and negatively charged exocyclic oxygen atoms in , and a monodentate bound through the negatively charged endocyclic nitrogen atom in .
