Crystal structure of sodium scandium bis(monohydrogenphosphate), NaSc(HPO4)2

Abstract

P205(-H20).Specimens could be isolated from suspensions with a typical composition of 0.500 g (3.626 mmol) SC2O3 (ABCR, 99.9 %), 1.383 g (3.626 mmol) Na4B 4 (>7 • 10H 2 0 (Aldrich, A.C.S.) and 6.688 g (58.008 mmol) phosphoric acid (85 %, Merck, p.a.) in 5 ml of water.Filled in 20 ml Teflon autoclaves (degree of filling: 30-40 %), the reaction mixture was kept at 443 K for six days.The raw product was filtrated and washed with water and acetone and finally dried in air at 333 K.
