Abstract
A novel inorganic-organic framework material has been prepared hydrothermally in the iron(II)-phosphate-oxalate system. Fe-4(PO4)(2)(C2O4)(H2O)(2) crystallizes in space group P2(1)/n, a = 7.974(3) Angstrom, b = 4.817(3) Angstrom, c = 14.169(3) Angstrom, beta = 94.70(3)degrees, V = 542.4(4) Angstrom(3), Z = 2, final R, R-w = 0.023, 0.025 for 817 observed data (I > 3 sigma(I)). The structure consists of sheets of interconnected FeO6, FeO5, and PO4 polyhedra in the ab plane, which are bridged via C2O42- groups along the c-axis to form an infinite three-dimensional network enclosing small cavities into which terminal FeOH2 groups protrude.
