Metal-halide complexes of a multidentate monoanionic ligand tBuN(H)SiMe2N(CH2CH2PiPr2)2, H[N2P2], with Ti, V, Cr, Mn, Fe, Co, and Ni have been isolated and characterized. X-ray crystallographic studies were performed on [N2P2]TiCl2 (3), [N2P2]CrCl2 (5), [N2P2]MnCl (6), [N2P2]FeCl (7), [N2P2]CoCl (8), and [N2P2]NiBr (9), and the results revealed that the [N2P2] ligand exhibits considerable flexibility
已分离并表征了多齿单阴离子配体tBuN(H)SiMe2N(CH2CH2PiPr2)2,H [N2P2]与Ti,V,Cr,Mn,Fe,Co和Ni的金属卤化物配合物。对[N2P2] TiCl2(3),[N2P2] CrCl2(5),[N2P2] MnCl(6),[N2P2] FeCl(7),[N2P2] CoCl(8)和[ N2P2] NiBr(9),结果表明[N2P2]配体以与第一行金属结合的方式表现出相当大的柔韧性,并且观察到三种不同的配位模式:kappa3-N2P(Ti),kappa3- NP2(Mn,Fe,Co)和kappa4-N2P2(Cr,Ni)。还描述了电化学(CV)数据和室温磁化率。
