Abstract

[Ph4P][B5O6(OH)4] · 1.5H2O (1) was obtained as colourless crystals in high yield from a MeOH/H2O solution of B(OH)3 and [PPh4][OH] (5:1). A single-crystal X-ray study confirmed that the solid-state structure was comprised of supramolecular networks of interconnected anions (H-bonds) and cations (phenyl embraces). Crystals are triclinic, P (1) over bar with a = 13.3174(3) angstrom, b = 13.3180(3) angstrom, c = 16.2055(4) angstrom, alpha = 91.1950(10)degrees, beta = 91.180(2)degrees, gamma = 105.456(2)degrees, T = 120(2) K, V = 2768.66(11) angstrom(3) and Z = 4. TGA/DSC analysis showed that 1 thermally decomposed in air at 800 degrees C to 2.5B2O3, via a low temperature dehydration step to a condensed pentaborate, [PPh4][B5O8].
