| Abstract: | A novel zinc diphosphonate, ZnHO3PCH2(C6H4)CH2PO3H] (1) was synthesized from tetraethyl para-xylylenediphosphonate, Et2O3PCH2C6H4CH2PO3Et2, and Zn (AcO)2·2H2O under solvothermal conditions. The structure of compound 1 was determined by single-crystal X-ray diffraction, which reveals that the structure crystallizes in the monoclinic space group C2/c (No. 15), with a = 22.4844(19) Å, b = 6.4361(5) Å, c = 8.1194(7) Å, β = 102.595(2)°, V = 1146.70(16) Å3, T = 298(2) K, Z = 8. The novel three-dimensional (3D) construction is simply built up from linear inorganic chains of corner-sharing four-rings of tetrahedral ZnO4] and PO3C] which connected adjacent chains by the organophosphorus ligand para-xylylenediphosphonate. The framework has 10 Å × 4 Å (containing the van der Waals radii of atoms) channels running along the b-axis. |
