Abstract
Abstract
It was found by derivatography and spectral measurements that the double complex salts, [Co(H2O)2N4] [Co(CN)6]·nH2O, where N4 is 4NH3, two moles of ethylenediamine (en) or one mole of triethylenetetramine (trien), [Co(NH3)2trien][Co(CN)6]·2H2O, [Co(NH3)tepa][Co(CN)6].2H2O, where tepa is tetraethylenepent-amine, and [Co(H2O)2trien][Cr(CN)6]·2H2O underwent deaquation-or deammonation-CN-bridging formation reaction upon heating. The general tendency was observed to be as follows: the more stable the structural configuration of the coordination sphere, the higher the activation energy. In the case of the complex containing hexacyanochromate(III) as an anion, the activation energy for the bridging formation reaction is especially high as a result of possible flipping in CN bridging groups.
