چکیده
In the title heterotrinuclear coordination compound, [CaCu(2)(C(9)H(4)NO(5))(2)(C(3)H(4)N(2))(2)(H(2)O)(3)]·7H(2)O, the Ca(2+) cation is in a penta-gonal-bipyramidal geometry and bridges two (1H-imidazole)[2-(oxaloamino)benzoato(3-)]copper(II) units in its equatorial plane. Each Cu(II) atom has a normal square-planar geometry. The mol-ecule has approximate local (non-crystallographic) mirror symmetry and 23 classical hydrogen bonds are found in the crystal structure.
