Abstract

NH4[NiGa1.84In0.16(PO4) 3(H2O)2] orthophosphate was prepared through hydrothermal synthesis and analyzed by means of single crystal X-ray diffractometry. It was solved within C2/c monoclinic space group; a = 13.2483(8)Å, b = 10.2468(8)Å, c = 8.9033(7)Å, bβ = 108.637(1)°, V = 1145.27(15)Å3. Phosphorous atoms display tetrahedral arrangement, occupying two distinct sites; Ni atoms form NiO4(OH 2)2 distorted octahedra, while Ga and In atoms share the same site forming (Ga,In)O5 units with trigonal bipyramidal geometry. (Ga,In)O5, NiO4(OH2)2 and PO 4 units are linked together through edge- and vertex-sharing arrangements, making up the three-dimensional framework, completed by (NH 4)+ counter-ions. Strong O-H⋯O and N-H⋯O hydrogen bonds contribute to stabilize the array: O-H⋯O interactions were also investigated by means of Libowitzky formula (Libowitzky, 1999) application, owing to the results of IR spectroscopy.
