Structural characterization of the coordination behavior of 4,4′-di-methoxy,2,2′-di-ol-benzophenone modified metal alkoxides

The coordination behavior of the 4,4′-di-methoxy,2,2′-di-ol-benzophenone (H2-OBzP) ligand with a series of early transition metal alkoxides (Group 4, 5, and 6) was determined to adopt either the 'bridging, chelating bridging' (μ,μc-OBzP) or the 'bichelating bridging' (μc2-OBzP) arrangement. The coordination mode appears to be driven by the need to satiate the Oh geometry.
