MoO2(C9H5NOH)2, Mr = 396,monoclinic,space group Cc,a = 13.369 (6), b = 9.408(4), c = 13.560(3)A,°=109.65°,V=1605A3,Z= 4,Dc= 1.639 g/cm3.R=0.027 for 1372 observed reflections [I>3o(I)]. X-ray analysis showed that the coordination sphere around molybdenum atom has a distorted octahedral geometry with two terminal oxygen atoms arranged in cis-form and two oxines act as bidentate ligands connected to the molybdenum through O and N atoms.Therefore, the molecule is not as Atovmyan described that the molybdenum atom is located on two-fold axis with space group C2/c but only approxiaately C2 synmetry. A = 13.369 (6), b = 9.408 (4), c = 13.560 (3) A, ° = 109.65 °, V = 1605A3, Z = 4 , Dc = 1.639 g / cm3.R = 0.027 for 1372 observed reflections [I> 3o (I)]. X-ray analysis showed that the coordination sphere around molybdenum atom has a distorted octahedral geometry with two terminal oxygen atoms arranged in cis- form and two oxines act as bidentate ligands connected to the molybdenum through O and N atoms. Before, the molecule is not as Atovmyan that that molybdenum atom is located on two-fold axis with space group C2 / c but only approxiaately C2 synmetry.
