Abstract

A series of Co(II)-1,10-phenanthroline-5,6-dione (phendione) complexes were prepared as scaffolds for the incorporation of pyrophosphate or methylenediphosphonate bridging ligands. Minor modifications in reaction conditions yielded the mononuclear complexes [Co(phendione)(H₂O)₄](SO₄)·2H₂O (1) and methylenediphosphonate complex [Co(phendione)(H₂O₃PCH₂PO₃H)(H₂O)₂]Cl·3H₂O (2). A bridged binuclear complex, [Co₂(phendione)₄(P₂O₇)]·nH₂O (3) was also prepared and structurally characterized. The magnetic properties of 3 were investigated.
