| Abstract: | The cobalt(II) chloride-2-nitroso-1-naphthol system has been studied spectrophotometrically in a 96:4 (v v ) benzene-ethanol solution. Two species have been found, the M:L complexation ratios of which are 1:1 and 1:2. The concentration quotients of the formation equilibria are K(1) = 1.2 x 10(3) and K(2) = 1.4 x 10(4) respectively. The first step of the reaction is accompanied by a configurational change from a tetrahedral to an octahedral structure. |
