摘要：
Aerobic reactions of Co(O2CMe)(2)center dot 4H(2)O with di-2-pyridyl ketone oxime (Hpko) in the presence of counterions (CIO4-, PF6-) give the tetranuclear, mixed-valence cobalt(II/III) clusters [Co-2(II)-Co-2(III)(OR)(2)(O2CMe)(2)(pko)(4)S-2]X-2 [R = H, S= MeOH, X = CIO4 (1); R = Me, S = EtOH, X = PF6 (2)] depending on the solvent mixture. Complexes 1 and 2 are the first Co members in the family of metallacrowns adopting the extremely rare inverse 12-metalla-crown-4 motif.
