A novel three-dimensional structure based on both mu(8)-bridging benzene-1,2,4,5-tetracarboxylate and mu(2)-bridging oxalate
This novel crystal structure of the coordination polymers {[M(mu(8)-bta)(1/2)(mu(2)-C2O4)(1/2)].(H2O)(4)}(n) (1: M = COIII; 2: M = Fe-III; bta = benzene-1, 2, 4, 5-tetracarboxylate) is based OD both bta and oxalate as bridging ligands and contains helical chains composed of left-handed and right-handed helices interlaced in pairs.
