Chemical preparation, X-ray single-crystal, thermal behaviour, and IR spectroscopy investigations are given for a new organic cation sulfate (C7H10NO)(2)SO4 (denoted BOAS) in the solid state. This compound crystallizes in the monoclinic space group P2(1)/c. The unit cell dimensions are: a = 7.010(3)angstrom, b = 11.142(5)angstrom, c = 20.770(8)angstrom, beta = 95.27(3)degrees with upsilon = 1615.4(12)angstrom(3) and Z = 4. The structure has been solved using a direct method and refined to a reliability R factor of 0.047. The title compound consists of a framework of isolated SO4 tetrahedral interleaved with organic molecules. so as to build isolated ribbons parallel to a-axis. In the present work, we describe the crystal structure, thermal behaviour and IR analysis of this new compound. (C) 2008 Elsevier Ltd. All rights reserved.
