The complexes of divalent Cobalt with bis(2,6-diacetyl pyridine monoxime)1,2-diiminobenzene have been prepared separately in presence of respective salts. The general molecular formula of the complexes have been found to be [Co(L)]X2 where L=Bis(2,6-diacetyl pyridine monoxime)1,2-di-iminobenzene, X=chloride, bromide, sulphate, perchlorate, nitrate, acetate ions, On the characterisation of the c...

Present studies show that nitrate accumulation is the major factor influencing the water uptake by vegetables, but there is lack of knowledge on how the relationship between nitrate and water concentrations in different vegetable tissues. We determined nitrate accumulation and water content in vegetables of rape, Chinese cabbage, and spinach under different nitrogen levels (experiment I), 29 sp...

Novel hydroxyamidinate complexes of cobalt(II) are presented, together with their electrochemical and spectroscopic properties. An unusual d(7) square-planar coordination around the cobalt(II) center exists and was confirmed by chemical oxidation to its Co(III) species. The Co(II) complex is difficult to reduce, but its facile oxidation suggests that it may be useful as an electron donor in pho...

The Bray-Liebhafsky (BL) oscillatory reaction generated in the batch reactor at 6268 C was perturbed by cobalt(II)-nitrate, supported on the macroreticular copolymer of poly-4-vinylpyridine with divinylbenzene (Co-PVPDVB). The kinetic data was analyzed of the complex pathways of the hydrogen peroxide decomposition in the examined BL reaction. The obtained results confirm that the kinetics of th...

Several cobalt complexes catalyze the evolution of hydrogen from acidic solutions, both homogeneously and at electrodes. The detailed molecular mechanisms of these transformations remain unresolved, largely owing to the fact that key reactive intermediates have eluded detection. One method of stabilizing reactive intermediates involves minimizing the overall reaction free-energy change. Here, w...
