<正> Trigallium tris(orthophosphate) hydrate-2-ethanolamine was synthesized from the ethanolamine(EAN)-Ga2O3-P2O5-H2O system. The compound crystallizes in monoclinic system, space group P21/n, with a = 8.669(2), b = 17.932(4), c = 9.097(2) A,β= 108.32(1)°,V=1342.4 A3, Z = 4. The structure was solved by direct methods and refined to final R of 0.048. For the three gallium atoms in an asymmetric unit, the coordination tetrahedron of Ga(3) is nearly regular, while Ga(l) and Ga(2) are each coordinated by five oxygen atoms and their coordination polyhedra show some distortion from a trigonal bipyramid. The three-dimensional net in the crystal lattice is built of two-dimensional nets which are composed of irregular triangles, quadrilaterals, pentagons and octagons formed by Ga and P atoms. Moreover, the corrugated 2D nets running along [101] are linked together by two double-crank-shaft chains of GaPO4, one of which runs along [101] while the other along [101]. The ethanolamine molecule, so called the template,
