摘要

Rubidium dihydrogentricyanomelaminate semihydrate Rb[H2C6N9] . 1/2 H2O was obtained as colorless rod-like single crystals from a solution of Rb-3[C6N9] . H2O and 0.1 M HCl after water evaporation at room temperature. According to the X-ray single-crystal structure determination (Rb[H2C6N9] . 1/2 H2O: C2/c (no. 15), a = 2007.4(3) pm, b = 512.2(l) pm, c = 2168.0(4) pm, beta = 11 1.66(2)degrees, Z = 8, R1 = 0.059, 2391 independent reflections, 159 parameters) Rb+ and cyclic planar [H2C6N9](-) ions as well as hydrate water molecules occur in the crystal. Rb[H2C6N9] . 1/2 H2O was investigated by FTIR and Raman spectroscopy, TG measurements and temperature-dependent X-ray powder diffraction. According to the thermoanalytic investigations, dehydration of Rb[H2C6N9] . 1/2 H2O starts above 60 degreesC and is finished below 250 degreesC.
