The crystal structure of bis-(2-hydroxyacetophenone) trimethylenediiminocopper(II), [Cu-(hapt)], has been determined on the basis of the X-ray diffraction data. The crystals are monoclinic. The cell dimensions are: <I>a</I>=17.746, <I>b</I>=9.467, <I>c</I>=10.646 Å, and β=114.06°. The space group is <I>Cc</I>, with four formula units in the unit cell. The structure has been refined from threedimensional data by the least-squares method with anisotropic temperature factors to an <I>R</I>-value of 0.093. The copper atom is four-covalent, with the two planar 2-hydroxyacetophenone groups oriented so as to give a flattened tetrahedral co-ordination geometry. The six-membered coppertrimethylenediamine ring takes a "twisted boat" configuration. The Cu–O bonds are 1.88 and 1.89 Å in length, while the Cu–N bonds are 1.94 and 1.97 Å. The angle between the mean planes of the 2-hydroxyacetophenone moieties is 46.2°.
