Porphyrin(2.1.2.1) as a novel binucleating ligand: synthesis and molecular structures of mono- and di-rhodium() complexes

The first example of monovalent and bimetallic porphyrins(2.1.2.1), the rhodium( i ) complex of porphyrin(2.1.2.1), was readily obtained under controlled conditions. The coordinated rhodium( i ) drastically influenced the molecular structure and optical and electronic properties. Our results clearly demonstrate that porphyrin(2.1.2.1) could be developed as a new binucleating ligand for the fabrication of bimetallic complexes. Porphyrin(2.1.2.1) could be developed as a new binucleating ligand for making bimetallic complexes.
