abstract: The tetra-nuclear title compound, [Cu(2)Ti(2)(C(6)H(6)NO(6))(2)O(O(2))(2)(H(2)O)(10)]·7H(2)O, lies about a twofold rotation axis that passes through the bridging oxide atom. The titanium atom is N,O,O',O''-chelated by the nitrilo-triacetate and O,O'-chelated by the peroidxo group and is coordinated to the bridging O atom in an overall penta-gonal-bipyramidal geometry. The O atom of one of the carboxyl-ate -CO(2) groups binds to the water-coordinated Cu atom, whose coordination polyhedron is an elongated octa-hedron. Adjacent tetra-nuclear mol-ecules are linked through the coordinated and uncoordinated water mol-ecules by O-H⋯O hydrogen bonds into a three-dimensional network.
