Abstract
Three novel palladium(II) mixed-ligand complexes of N-(benzothiazol-2-yl)benzamide (HL) and 1,2-bis(diphenylphosphino)ethane (dppe), [Pd(HL)(dppe)]Cl2 (1), [Pd(L)(dppe)]Cl (2), and [Pd(L)2(dppe)] (3), were synthesized and fully characterized using Fourier transform infrared, 1H, 13C, and 31P NMR, and molar conductivity measurements. Complex 3 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 1, a negatively charged L bound as a bidentate chelate through the endocyclic nitrogen and negatively charged exocyclic oxygen atoms in 2, and a monodentate bound through the negatively charged endocyclic nitrogen atom in 3.
