Abstract

Physico-chemical properties of a new organic bismuthate(III), [C2H5N4]4Bi2Cl10 are discussed on the basis\ud of X-ray crystal structure investigation. This compound crystallizes in the monoclinic space group C2/c,\ud with a = 16.3622(3), b = 12.7941(2), c = 14.8178(2) Å, b = 98.5660(10), V = 3067.35(8) Å3 and Z = 4. The\ud crystal structure consists of discrete binuclear [Bi2Cl10]4 anions and 3-amino-1-H-1,2,4-triazolium\ud cations. The crystal packing is governed by strong N-H...N and weak N-H...Cl hydrogen bonds and\ud Pi...Pi stacking interactions to form three-dimensional network. The 13C CP-MAS NMR spectrum is in\ud agreement with the X-ray structure. The infrared study confirms the presence of the organic cation\ud [C2H5N4]+. The vibrational absorption bands were identified by infrared spectroscopy and DFT calculations\ud allowed their attribution
