Sažetak
The crystal structure of the title complex has been determined by X-ray diffraction at room temperature. Monoclinic crystals of C20H24CuN2O4 have space group P2l/n with unit cell dimensions a = 11.832(2) Å, b = 11.981(5) Å, c = 14.764(5) Å, β = 112.20(2)°, Z = 4, Dx = 1.44 and Dm = 1.44 Mg m−3 (by flotation). The structure was refined by a full-matrix procedure on 1771 reflections to final R = 0.069. The copper atom in the structure exists in a square-planar geometry formed by two O and two N atoms of two salicylideneaminato ligands. The molecule is almost planar with the perpendicular distance between Cu atom and the benzene ring planes from two salicylideneaminato ligands of 0.006(1) Å and 0.003(1) Å, respectively. In order to compare these results with those in the analogous structures of bis(N-phenylsalicylideneaminato)copper(II) and bis(N-2-hydroxyethylsalicylideneaminato)copper(II), the two latter structures have been redetermined by us and are published as New Crystal Structures on pages 728–730
