Abstract

Using H3PO3 as a phosphorus source and oxalic acid as a reducing agent, the first three-dimensional open-framework gallium phosphate-phosphite formula as (C6N2H18)2(C6N2H17)Ga15(OH)8(PO4)2(HPO4)12(HPO3)6·2H2O (1), has been hydrothermally synthesized in the presence of N,N,N′,N′-tetramethylenediamine (TMEDA) as a structure-directing agent. Compound 1 crystallizes in trigonal system with space group P - 3, a = b = 19.046(3) Å, c = 8.3306(17) Å, γ = 120°, V = 2617.1(7) Å3, and Z = 1. Its 3-D network is based on alternated Ga-centered (GaO4 tetrahedra, GaO5 trigonal bipyramids, and GaO6 octahedra) and P-centered (PO43-, HPO42-, and HPO32-) units. Protonated organic amines and water molecules are located in the 12-membered ring channels.
