The paper reports the syntheses and characterization of two phosphonate compounds with layered structures, namely, Mn{sub 2}(2-C{sub 5}H{sub 4}NPO{sub 3}){sub 2}(H{sub 2}O) (1) and Zn(6-Me-2-C{sub 5}H{sub 4}NPO{sub 3}) (2). In compound 1, double chains are found in which the {l_brace}Mn{sub 2}O{sub 2}{r_brace} dimers are linked by both aqua and O-P-O bridges. These double chains are connected through corner-sharing of {l_brace}MnO{sub 5}N{r_brace} octahedra and {l_brace}CPO{sub 3}{r_brace} tetrahedra, forming an inorganic layer. The pyridyl groups fill the inter-layer spaces. In compound 2, each {l_brace}ZnO{sub 3}N{r_brace} tetrahedron is vertex-shared with three {l_brace}CPO{sub 3}{r_brace} tetrahedra and vice versa, hence forming an inorganic honeycomb layer. The pyridyl groups reside between the layers. Magnetic studies show that weak antiferromagnetic interactions are mediated between the manganese ions in compound 1. Crystal data for 1: monoclinic, space group C2/c, a=29.611(7)A, b=5.307(1)A, c=9.844(2)A, {beta}=107.3(1){sup o}. For 2: orthorhombic, space group Pbca, a=10.305(2)A, b=9.493(2)A, c=15.603(3)A.
