Abstract

The interactions of cyclic trinuclear copper {[3,5-(CF3)2Pz]Cu}3 and silver {[3,5-(CF3)2Pz]Ag}3 complexes with polyhedral borate anions [B10H10]2− and [B12H12]2− in solvents of low-polarity were studied using IR spectroscopy (190–290 K). Two types of complexes were found in solution: {[((3,5-CF3)2PzM)3][BnHn]}2− and {[((3,5-CF3)2PzM)3]2[BnHn]}2− (M = Ag, Cu; n = 10, 12). The stability constants of these complexes were determined from IR-spectra.
