摘要
The tetranuclear title compound, [Cu2Ti2(C6H6NO6)(2)O(O-2)(2)(H2O)(10)]center dot 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 nitrilotriacetate and O,O'-chelated by the peroidxo group and is coordinated to the bridging O atom in an overall pentagonal-bipyramidal geometry. The O atom of one of the carboxylate -CO2 groups binds to the water-coordinated Cu atom, whose coordination polyhedron is an elongated octahedron. Adjacent tetranuclear molecules are linked through the coordinated and uncoordinated water molecules by O-H center dot center dot center dot O hydrogen bonds into a three-dimensional network.
