Description
A new iron phosphonate-oxalate [Fe(O3PCH3)(C2O4)0.5(H2O)] (1), has been synthesized under hydrothermal condition. The single-crystal X-ray diffraction studies reveal that 1 consists of layers of vertex-linked FeO6 octahedra and O3PC tetrahedra, which are further connected by bis-chelate oxalate bridges, giving to a 3D structure with 10-membered channels. Crystal data: monoclinic, P21/n (no. 14), a=4.851(2)A, b=16.803(7)A, c=7.941(4)A, β=107.516(6)o, V=617.2(5)A3, Z=4, R1=0.0337 and wR2=0.0874 for 1251 reflections [I>2σ(I)]. Mossbauer spectroscopy measurement confirms the existence of high-spin Fe(III) in 1. Magnetic studies show that 1 exhibits weak ferromagnetism with TN=30K due to a weak spin canting
