title: trans-bis(3-aminoflavone-kappa2N,O)bis(perchlorato-kappaO)copper(II), a new potential antitumour agent.
abstract: The title compound, trans-bis(3-amino-2-phenyl-4H-1-benzopyran-4-one-kappa(2)N,O(4))bis(perchlorato-kappaO)copper(II), [Cu(ClO4)2(C(15)H(11)NO(2))2], is composed of mononuclear units wherein the central Cu(II) cation occupies a crystallographic inversion centre. The cation is coordinated by two bidentate 3-aminoflavone ligands occupying the equatorial sites and by two perchlorate anions in the apical positions, thereby giving rise to a markedly elongated octahedral coordination geometry. Two symmetry-related intermolecular N-H...O hydrogen bonds link the molecules into chains of rings running parallel to the [100] direction, while intramolecular N-H...O hydrogen bonds help to determine the orientation of the apical perchlorate anions.
