Crystal Structure of Dichloro{2-(quinolin-2-yl)-4H-benzo[d][1,3]oxazine}cobalt(II)

The title compound, [CoCl2(qboz)], [qboz = 2-(quinolin-2-yl)-4H-benzo[d][1,3]oxazine], was synthesized and characterized by single-crystal X-ray analysis. This compound crystallizes in the triclinic space group P1 with cell parameters of a = 7.996(5)angstrom, b = 8.580(6)angstrom, c = 12.508(8)angstrom, alpha = 99.154(11)degrees, beta = 93.012(11)degrees, gamma = 108.108(8)degrees, V = 800.5(9)angstrom(3), D-calcd = 1.618 g/cm(3), Z = 2. The R1 [I > 2 sigma(I)] and wR2 (all data) values are 0.0345 and 0.0875, respectively, for all 3549 independent reflections. The benzoxazine ligand is believed to have been obtained by the nucleophilic addition of benzyl alcohol to imine carbon and the subsequent metal-catalyzed air oxidation of the Schiff-base ligand.
