✦ Synopsis

A novel inorganic-organic framework material has been prepared hydrothermally in the iron(II)-phosphate-oxalate system. Fe4(PO4)2(C2O4)(H2O)2 crystallizes in space group P21/n, a ‫؍‬ 7.974(3) A s , b ‫؍‬ 4.817(3) A s , c ‫؍‬ 14.169(3) A s , ‫؍‬ 94.70(3)°, V ‫؍‬ 542.4(4) A s 3 , Z ‫؍‬ 2, final R, R ‫؍‬ 0.023, 0.025 for 817 observed data (I'3 (I)). The structure consists of sheets of interconnected FeO6, FeO5, and PO4 polyhedra in the ab plane, which are bridged via C2O 2؊ 4 groups along the c-axis to form an infinite three-dimensional network enclosing small cavities into which terminal FeOH2 groups protrude.
