摘要：

Reaction of [Cr3O(O(2)CPh)(6)(H2O)(3)]NO3 in PhCN with NEt(3) and picolinic acid followed by recrystallization of the resulting solid from CH2Cl2-hexanes affords green crystals of [NEt(3)H] [Cr4O2(O(2)CPh)(7)(pic)(2)] (1). The X-ray crystal structure reveals the presence of a di(mu-oxo) tetrachromium(III) core in the anion, which combines two structural elements previously proposed as important for the biological activity of chromium.
