Abstract

The synthesis of cobalt(II), nickel(II) and zinc(II) complexes of 2-pyridine-2-yl-3(pyridine-2-carboxylideneamino)1,2-dihydroquinazolin-4(3H)-one is described. The ligand and metal complexes were characterized by elemental analysis, conductivity measurements, spectral (u.v.-vis.,i.r., 1D n.m.r., 2D hetcor and mass) and thermal studies. The cobalt(II) complex crystallizes as pink crystals in the monoclinic crystal system, space group P21/n with a = 10.066(6) Angstrom over circle, b= 15.929(9) Angstrom over circle, c = 12.624(7) Angstrom over circle, \alpha =90.00(9)degrees, \beta = 110.850 (8)degrees, \gamma = 90.00, V = 1891.5(18) Angstrom over circle (3) and Z = 4. The geometry around the cobalt atomis distorted trigonal bipyramidal with T = 0.83 [structuralparameter, T = (\beta - \alpha)/60; where \alpha and \beta are the two basal angles in a five coordinate complex].
