Abstract
Crystals of a new hybrid compound C8H12N+, HSO4-center dot H2O were synthesized in aqueous solution and characterized by X-ray diffraction and IR absorption spectroscopy. This compound crystallizes in the orthorhombic non-centrosymmetrical space group P2(1)2(1)2(1) and an unit cell with a = 5.74(2) angstrom, b = 9.17(2) angstrom, c = 21.34(4) angstrom, V = 1124(6) angstrom(3), and Z = 4. Its crystal structure is a packing of alternated inorganic and organic layers parallel to (a, b) planes. The different components are connected by a bi-dimensional network of strong O-H center dot center dot center dot O and N-H center dot center dot center dot O hydrogen bonds. Then, in order to detect phase transitions and watch changes in the conductivity behaviour, investigations by DTA-TG and differential scanning calorimetry (DSC) and electrical conductivity measurements were carried out.
