title: Ga(2,2'-bipy)(HPO(4))(H(2)PO(4)): first layered inorganic-organic hybrid gallium phosphate with a neutral framework.
abstract: A novel gallium phosphate, Ga(2,2'-bipy)(HPO(4))(H(2)PO(4)) (denoted FJ-12; FJ = Fujian Institute of Research on the Structure of Matter), which is the first example of layered inorganic-organic hybrid gallium phosphate with neutral framework, has been hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction. This compound crystallizes in the monoclinic system, space group P2(1)/c (No. 14), with a = 10.9443(9), b = 15.8253(13), and c = 8.4201(7) A, beta = 108.898(2) degrees, V = 1379.7(2) A(3), and Z = 4. The structure consists of HPO(4) and H(2)PO(4) tetrahedra and unusual GaO(4)N(2) octahedra which are linked through their vertexes forming an undulated sheetlike structure with 4.12-net. The adjacent layers are stably packed together and exhibit interesting 3-D supramolecular arrays pi-pi interactions of the 2,2'-bipy groups.
