Correction to Unsymmetrical Chelation of N-Thioether-Functionalized Bis(diphenylphosphino)amine-Type Ligands and Substituent Effects on the Nuclearity of Iron(II) Complexes: Structures, Magnetism, and Bonding

Tetracarbonyl group 6B metal complexes of a N-(4-acetylphenyl)-N-(diphenylphosphino)amine ligand. Molecular structure of cis-[Cr(CO)4{4-CH3CO-C6H4-1-N(PPh2)2}]

Chemical reactions of N-(4-acetylphenyl)-N-(diphenylphosphino)amine ligand (1) with three group 6B metal hexacarbonyls produced cis-M(CO)₄[1-_k ² P,P][ M = Cr(2), Mo(3), W(4)], respectively. The novel complexes 2-4 were isolated and their structures were elucidated by multinuclear NMR spectroscopy (¹H, ¹³C, ³¹P NMR) and elemental analysis. Crystal-structure determination using single-crystal X-ray diffraction was carried out on complex 2.
