Abstract: A gallophosphate, Ga3P3O12·H2O·H2NCH2CH2NH2, named GaPO4-C4 was hydrothermally synthesized from EDA(ethylenediamine)-Ga2O3-P2O5-H2O systems. The crystal structure of GaPO4-C4 was determined by single crystal X-ray diffraction. The compound crystallizes in monoclinic system with space group P21/n, a=8.688(4)Å, b = 17.952(6)Å, c=9.104(3)Å, β=108.27(3), V=1348.3Å3 . The framework of GaPO4-C4 contains three types of P atoms and three types of Ga atoms. Of the three types of gallium atoms, two types are located in distorted trigonal bipyramids and the third type lies at tetrahedral centre. The three-dimensional framework is built of two-dimensional nets which consist of irregular 3-, 4-, 5- and 8-rings and contains 8-ring channels running along [101], in which ethylenediamine templates are located.
