Hydrothermal synthesis and characterization of CsNiP and 2(LiZnHP2O7) crystals

CsNiP and 2(LiZnHP2O7) crystals were synthesized by hydrothermal technique at moderate P-T conditions. Solubility results of both the compound shown positive thermal coefficient and single crystal X-ray studies revealed, CsNiP crystallized in hexagonal system with cell parameters; a = 7.173(2), c = 5.944(9)A° , V = 264.87(7)A° 3 and space group P63/mmc and 2(LiZnHP2O7) crystallized in orthorhombic system with cell parameters; a = 12.3636A° , b = 27.5330A° , c = 6.8647A° and space group, Pca21 exhibiting ring type of cavities with open aperture in the structure. CsNiP is a frequency dependent paramagnetic and 2(LiZnHP2O7) is a diamagnetic. C 2006 Springer Science + Business Media, Inc.
