| Abstract: | Summary Several new polymeric complexes of general composition MOn(L)4X2 (where M = V, Zr and U; n = 1 or 2; X = Cl, Br, I, NO3 and NCS and L = N2H4, PhNHNH2 and Me2NNH2 have been synthesised and characterized by elemental and d.t. analyses and by magnetic measurements, electronic and i.r. spectra. The vanadyl(IV) complexes exhibit subnormal magnetic moments (1.26–1.36BM) possibly because of exchange interaction between vanadium(IV) ions. The thermal stability of hydrazine complexes fall in the order: Cl>Br>NCS>I. The M-N bond strength, as revealed, by v(M-N), decreases as: Me2NNH2>N2H4>PhNHNH2.Presented in symposium on Frontiers of coordination chemistry, Allahabad University, Allahabad, Dec. 6–8, 1979. |
