Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Organometallics called Synthesis and Characterization of a N,C,N-Carbodiphosphorane Pincer Ligand and Its Complexes, Author is Klein, Marius; Xie, Xiulan; Burghaus, Olaf; Sundermeyer, Joerg, which mentions a compound: 37943-90-1, SMILESS is P(C1=CC=CC=C1)(C2=CC=CC=C2)C3=NC=CC=C3, Molecular C17H14NP, Quality Control of Diphenyl-2-pyridylphosphine.
The reaction of 2-pyridiyldiphenylphosphine (2) with tetrachloromethane and subsequent dehalogenation of the intermediate chloro phosphonium salt [(CDPPy2)Cl]Cl (3) with tris(1-pyrrolidyl)phosphine gave a new type of carbodiphosphorane N,C,N pincer ligand, sym-bis(2-pyridyl)tetraphenylcarbodiphosphorane, CDPPy2 (1). It crystallizes in a triclinic crystal system with a crystallog. point group of P1̅. This neutral double-ylidic N,C,N ligand is capable of stabilizing a wide range of metal coordination polyhedra, varying from square planar [(CDPPy2)PdCl]Cl (4), octahedral mer-[(CDPPy2)TiCl3] (5) and fac-[(CDPPy2)Cr(CO)3] (6) to trigonal-bipyramidal [(CDPPy2)MnCl2] (9) and [(CDPPy2)CoCl2] (10) complexes. Unprecedented dinuclear complexes are formed with Mo and Ni carbonyls. 1 reacts with [Mo(CO)3(NCMe)3] to form the sym. κ3-N,C,N-[(CDPPy2)Mo(CO)3(μ-CO)Mo(CO)3] (7) with one bridging carbonyl next to a bridging central C atom with its two lone pairs. In contrast, an unsym. coordination mode with only one coordinated pyridine is observed in κ2-N,C-[(CDPPy2)Ni(CO)(μ-CO)Ni(CO)2] (8). Carbodiphosphorane-based ligands are unique due to their σ,π four-electron-donor character of the central C atom toward one metal and alternatively their 2σ four-electron-donor character toward two vicinal metal atoms.
