| Abstract: | Report of the preparation, chemical properties, and the infrared-to-ultra-violet spectra of the perchlorates and bromides of the two complex cations Co2{ac(OH)2}(NH3)6]3+ (where ac = HCO2, CH3CO2; CH2ClCO2, CHCl2CO2, CCl3CO2, CHFCO2, CHF2CO2 und CF3CO2) and Co2{ac2(OH)}(NH3)6]3+ (where ac = CH2ClCO2, CHClCO2 und CCl3CO2). The perchlorate, nitrate, bromide and dithionate salts of the tetranuclear complex Co4{C2O4(OH)4}(NH3)12]6+ are described. The complex reported by WERNER as Co2{OH}2(CH3CO2)H2O(NH3)6]Br3 actually has the formula Co2{CH3CO2(OH)2}(NH3)6]Br3 · CH3COOH. |
