Porphyrins and polyoxometalates are widely studied molecules because of their tunable physical and chemical properties. A ternary complex is formed when HfIV or ZrIV metal ions coordinate both a porphyrin and a lacunary defect in a polyoxometalate. A crystal structure of a HfIV complex and spectroscopic data suggest that HfIV or ZrIV porphyrins can bind to oxide surfaces by the protruding metal ion.
