A new iron phosphonate-oxalate [Fe(O{sub 3}PCH{sub 3})(C{sub 2}O{sub 4}){sub 0.5}(H{sub 2}O)] (1), has been synthesized under hydrothermal condition. The single-crystal X-ray diffraction studies reveal that 1 consists of layers of vertex-linked FeO{sub 6} octahedra and O{sub 3}PC tetrahedra, which are further connected by bis-chelate oxalate bridges, giving to a 3D structure with 10-membered channels. Crystal data: monoclinic, P2{sub 1}/n (no. 14), a=4.851(2)A, b=16.803(7)A, c=7.941(4)A, {beta}=107.516(6){sup o}, V=617.2(5)A{sup 3}, Z=4, R{sub 1}=0.0337 and wR{sub 2}=0.0874 for 1251 reflections [I>2{sigma}(I)]. Mossbauer spectroscopy measurement confirms the existence of high-spin Fe(III) in 1. Magnetic studies show that 1 exhibits weak ferromagnetism with T{sub N}=30K due to a weak spin canting.
