Hydrolysis of di-Et 6-chloro-2-pyridinephosphonate in HCl solution affords 6-hydroxy-2-pyridinephosphonic acid (H2hppa 1). In the structure, extensive hydrogen bonding interactions link the phosphonic acid mols. into a two-dimensional network. Reactions of H2hppa and cobalt acetate under hydrothermal conditions result in a new cobalt phosphonate Co(hppa)(H2O) (2). Compound 2 shows a layer structure, in which {Co2O2} dimers are connected through the corner-sharing of {CoO5N} octahedra and {PO3C} tetrahedra, forming an inorganic double-layer. Introduction of a second ligand (1,4-bis(imidazol-1-ylmethyl)benzene, L (8)) in the reaction system, compound [Co(hppa)(L)0.5(H2O)]·H2O (3) was obtained. In this structure, Co2+ ions are bridged by O-P-O bridges into an inorganic layer and the layers are pillared up by 1,4-bis(imidazol-1-ylmethyl)benzene. Magnetic study suggests that the existence of weak ferromagnetic coupling between Co2+ ions in the {Co2O2} unit for 2. For compound 3, O-P-O bridges mediate very weak antiferromagnetic interactions.
After consulting a lot of data, we found that this compound(2402-95-1)Computed Properties of C5H4ClNO can be used in many types of reactions. And in most cases, this compound has more advantages.
