Deskripsi
The tetranuclear title compound, [Cu2Ti2(C6H6NO6)2O(O2)2(H2O)10]·7H2O, 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...O hydrogen bonds into a three-dimensional network.
