This paper reports the syntheses and characterization of two phosphonate compounds Cd{(2-C5H4NO)CH(OH)PO3}(H2O)2 (1) and Zn{(4-C5H4NO)CH(OH)PO3} (2) based on hydroxy(2-pyridyl N-oxide)methylphosphonic and hydroxy(4-pyridyl N-oxide)methylphosphonic acids. Compound 1 has a chain structure in which dimers of edge-shared {CdO6} octahedra are linked by {CPO3} tetrahedra through corner-sharing. The pyridyl rings reside on the two sides of the inorganic chain. Compound 2 has a layer structure where the inorganic chains made up of corner-sharing {ZnO4} and {CPO3} tetrahedra are covalently connected by pyridyl N-oxide groups. Crystal data for 1: triclinic, space group P1¯, a=6.834(1) Å, b=7.539(1) Å, c=10.595(2) Å, α=84.628(3)°, β=74.975(4)°, γ=69.953(4)°. For 2: triclinic, space group P1¯, a=5.219(1) Å, b=8.808(2) Å, c=9.270(2) Å, α=105.618(5)°, β=95.179(4)°, γ=94.699(4)°.
