2-2-(oxaloamino)benzoato(3-)]dicopper(II)calcium(II) heptahydrateAbstract: In the title heterotrinuclear coordination compound, [CaCu2(C9H4NO5)2(C3H4N2)2(H2O)3]·7H2O, the Ca2+ cation is in a pentagonal-bipyramidal geometry and bridges two (1H-imidazole)[2-(oxaloamino)benzoato(3-)]copper(II) units in its equatorial plane. Each CuII atom has a normal square-planar geometry. The molecule has approximate local (non-crystallographic) mirror symmetry and 23 classical hydrogen bonds are found in the crystal structure.
