Abstract
  • NH 4[NiGa 1.84In 0.16(PO 4) 3(H 2O) 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, b? = 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)O 5 units with trigonal bipyramidal geometry. (Ga,In)O 5, NiO 4(OH 2) 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 (literal)
