| 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]2BnHn]}2− (M = Ag, Cu; n = 10, 12). The stability constants of these complexes were determined from IR-spectra. |
