Abstract

Single crystals of the tetraethylammonium dihydrogenmonophosphate bis trihydrogenmonophosphate       3 2 2 4 3 4 4 CH CH N H PO H PO TEP    2, were grown by slow evaporation solution technique at room temperature.The compound was characterised by IR, Raman, differential thermal analysis (TG-DTA) and single crystal X-ray diffraction. It crystallizes in the monoclinic system (space group 1 2 P c) with the following unit cell dimensions: a = 7.765 (2) Å, b = 16.531 (4) Å, c = 14.843 (2) Å, β = 100.99 (2)˚, 4 Z  , 3

Crystal structure, thermal behavior and vibrational studies of tetraethylammonium dihydrogenarsenate bis-arsenic acid [(C2H5)4N].[H2AsO4].[H3AsO4]2

“…The C-C bonds lengths are in the region between 1.477(13) to 1.611(14) Å. They are in good agreement with those found in related compound [19,21].…”

“…However, in conjunction with some resent works on these hybrids compounds, the crystal structure and vibrational studies of many organic-inorganic crystals have been investigated in our laboratory [19][20][21]. The present work deals with the growth, single crystal X-ray diffraction (XRD) study, thermal analysis and the detailed vibrational spectral analysis of a new organic-inorganic: tetraetylammonium dihydrogen monoarsenate bis-arsenic acid (TEAs).…”

“…One feature is the strong absorption at ~3000 cm −1 , indicating the OH group. In this region, a stretch at around 2920 cm −1 in burned TPN3-20 corresponds to the P-OH [46,47]. A closer look at the burned TPN1-18 reveals a similar absorption at 2655 cm −1 .…”
