Abstract

Two isostructural transition-metal oxalatophosphonates, Na2M3(C2O4)3(CH3PO3H)2 (M = Fe(II) and Mn(II)), have been synthesized by using a low-melting-point eutectic mixture of choline chloride and malonic acid as a solvent and characterized by single-crystal X-ray diffraction and 57Fe Mössbauer spectroscopy. The 3D framework structure consists of a corner-sharing octahedral trimer that is linked with other trimers through two distinct oxalate ligands with unusual linkage types, phosphonate tetrahedra, and H bonds to form infinite channels along the [101] direction where the Na+ cations are located. They are the first examples for the use of an ionic liquid as a solvent in the synthesis of metal oxalatophosphonates. Crystal data for the Fe compound follow: monoclinic, P2(1)/n (No. 14), a = 5.8063(1) A, b = 10.3867(3) A, c = 14.8094(4) A, beta = 96.926(1) degrees , and Z = 2. Crystal data for the Mn compound are the same as those for the Fe compound except a = 5.8734(9) A, b = 10.557(2) A, c = 14.863(2) A, and beta = 96.691(2) degrees .
