Abstract
The complex formation between redox active 2,4,6,8-tetrakis(tert-butyl)phenoxazin-1-one (L) and four-coordinate Co(II) complexes, resulting in six-coordinate adducts (I) (C77H82N12O5Co) and (II) (C38H41NO6F12Co) was studied. High-spin structure of the formed cobalt adducts I and II (hs-CoII–BQ) was established by X-ray diffraction analysis and magnetochemistry methods. Adducts I and II are stable over a wide temperature range (5–300 K) and are not involved in the redox process giving low-spin adducts (ls-CoIII–SQ) studied previously.
