Abstract
Crystals of 2(2-ammonium ethyl ammonium)ethanol sulfate monohydrate: (C4H14N2O)SO4·H2O abbreviated as AEESM, and 2(2-ammonium ethyl ammonium)ethanol sulfate: (C4H14N2O)SO4 abbreviated as AEES, have been prepared and grown at room temperature. These materials have the following unit cell dimensions (C4H14N2O)SO4·H2O: a = 16.116(6), b = 7.411(3), and c = 15.750(6) Ã
; (C4H14N2O)SO4: a = 8.1142(2), b = 10.6632(4), c = 9.9951(4) Ã
, and β = 99.433(3)°. Their space groups are Pbca and P21/c, respectively. The structures of these compounds have been determined by single-crystal X-ray data analysis. The AEESM structure is built up from infinite inorganic chains parallel to the b axis linked via Ow-Hâ¯O hydrogen bonds. These chains are interconnected by organic groups so as to build layers perpendicular to the c direction. The structure of AEES consists of a three-dimensional network of H-bonds connecting all its components. In the present work the crystal structures, thermal behavior and IR analysis of these two new compounds are described.
