[N,N'-(4-Methyl-4-azaheptane-1,7-diyl-kappaN)bis(4-methoxysalicylideniminato-kappa4O,N,N',O')]cobalt(II) ethanol hemisolvate.

The title compound, [Co(C(23)H(29)N(3)O(4))].0.5C(2)H(6)O or [Co(II)[(4-MeO-sal)(2)Medpt]].0.5CH(3)CH(2)OH [(4-MeO-sal)(2)Medpt is N,N'-(4-methyl-4-azaheptane-1,7-diyl)bis(4-methoxysalicylideniminate)], obtained through the reaction of H(2)[(4-MeO-sal)(2)Medpt] and Co(CH(3)COO)(2) in refluxing ethanol under an atmosphere of ultrapure nitrogen, has the usual pseudo-trigonal-bipyramidal coordination arrangement previously found for this class of (sal)(2)Rdpt compounds. The O-Co-O bond angle [120.4 (1) degrees] is significantly smaller than the corresponding values previously found for most non-O(2)-bound [Co(II)[(sal)(2)Medpt]]-type molecules (observed range 126.9-138.6 degrees), whereas the equatorial Co-N bond [2.185 (3) A] is relatively long.
