Poly[(₄-3-pyridylphosphonato-⁴-N:O:O':O'')cobalt(II)]

A. E. Wasson and R. L. LaDuca

Abstract: The title compound, [Co(C₅H₄NPO₃)]_n, is a three-dimensional network coordination polymer containing tetrahedrally coordinated Co^II bound to one N atom from one 3-pyridylphosphonate ligand and three O atoms, each from three other distinct 3-pyridylphosphonate ligands. The structure exhibits two-dimensional cobalt phosphonate layers, parallel to the ac crystal plane, constructed from the junction of Co₃O₆P₃ 12-membered rings. The inorganic layers are pillared through the N-atom donors of the tethering pyridyl rings to produce the three-dimensional crystal structure of (I).
