摘要: The electronic effect of substi- tuting CH with N in poly(pyrazoly1)- borato ligands and their transition-metal complexes is shown to be a decrease energy the filled metal ligand or- bitals. This conclusion based on cyclovoltammograms photoelectron spectra bis(hydrotris(azoly1)borato)- iron(") -cobalt(It) (azolyl = pyrazolyl 1,2,4-triazolyl) bis(hydrotris(l,2,4-triazolyl)- borato)iron(rI) show that there fine- tuning HOMO-LUMO gap by shift transition temperature for spin
