Abstract

[Cu(C~4H~oBr2NO)2], Mr=799.6, monoclinic, P2~/n, a=17.866(5), b=21-963(6), c = 14.128 (4) A, ,8 = 93"16 (2) ° V = 5535 (2) A 3, Z= 8, Dx =l'919Mgm -3, /z=6.54mm -~, A(MoKa) = 0-71069 A, F(000) = 3096, T= 293 K, final R = 0-076 for 5411 unique observed reflections with F > 3tr(F). The two crystallographically independent molecules have a nearly identical distorted planar coordination about the Cu atoms. The angles between the two coordination planes defined by O1--Cu--N1 and O2---Cu--N2 are 33.4 and 33.7 ° for molecules 1 and 2, respectively. The mean N---Cu--N and N---Cu--O bond angles are 155-0 (4) and 92.5 (12) °, the mean Cu--N and Cu---O bond lengths are 1.963 (12) and 1.885 (3)A, respectively. No interaction is possible between Cu atoms.
