Исследование строения комплексных соединений тетрафторбората меди (II) c n-замещенными тетразолами методом ИК-спектроскопии

Abstract

Coordination of the BF4 anion with central atom in complexes of copper (II) tetrafluoroborate with Tethyl-(1-ET), 2-ethyl- (2-ET), 1-butyl- (TBuT)1 1-phenyl- (TPhT)1 1-fert-butyl- (Tf-BuT) and 2-fert-butyttetrazdes (2-f-BuT) have been investigated using IR spectroscopy It was established that in complexes with ratio Cu/L = 1/4, (1^1-ET 2-ET, Tf-BuT and 2-f-BuT) two BF; anion are bonded with copper (II) atom via fluorin atom whereas in complexes with ratio Cu/L = 1/6, (L=1-ET, 1-BuT) two BF4 anions are not coordinated. Complex Cu(I-PhT)5(BF4)2 have intermediate structure and BF . anions are in both tree and coordinated forms.
