Abstract
Abstract The X-ray structure of tetraethylammonium hydrogenselenate, [N(C2H5)4]HSeO4, was determined at room temperature. The crystal belongs to the P1 space group of triclinic system, Z=2, a=8.290(2), b=9.073(2), c=9.517(2) A , α=76.75(3), β=74.31(3) and γ=63.92(3)°. The hydrogenselenate anions are joined into cyclic dimers by two identical (equivalent by Ci) strong hydrogen bonds O(2)–H(02)⋯O(1a); the O(2)⋯O(1a) distance equals 2.611(5) A. Powder IR and Raman spectra are discussed with respect to the crystal structure. The DSC reveals two phase transitions at 328 and 358 K.
