Order-disorder phase transition in the peroxidovanadium complex NH4[VO(O2)2(NH3)]
Autor: Přemysl Vaněk, Róbert Gyepes, Peter Schwendt, Jana Chrappová, Ivan Němec
Publikováno v: Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy. 200:110-115
Complex NH4[VO(O2)2(NH3)] (1) undergoes an order-disorder phase transition at Tc ~ 258 K. This transition is accompanied by change in the space group of the orthorhombic lattice and also by significant structural rearrangements of the constituent mol
