Abstract (EN):
The cobalt(tl) species resulting from room-temperature photolysis of aqua(sec-butyl)bis(dimethyl-glyoximato)cobalt(III) [Co-III(Hdmg)(2)Bu(s)(H2O)] solutions in the presence of various amounts of each of 27 different N-donor bases L were studied by electron spin resonance spectroscopy and the ESR spectra compared, when possible, with those of irradiated solutions of the corresponding [Co-III(Hdmg)(2)Bu(s)(L)] compounds. From the ESR results. the bases could be grouped according to the position of the substituents. Both base strength and steric effects seem to play a role in the formation of 1:1 and 1:2 cobalt(II) adducts although no definite correlation between the ESR parameters determined for the various species and basicity was found.
