Abstract
Reaction of [Cr3O(O(2)CPh)(6)(H2O)(3)]NO3 in PhCN with NEt(3) and pico linic acid followed by recrystallization of the resulting solid from C H2Cl2-hexanes affords green crystals of [NEt(3)H] [Cr4O2(O(2)CPh)(7)(p ic)(2)] (1). The X-ray crystal structure reveals the presence of a di( mu-oxo) tetrachromium(III) core in the anion, which combines two struc tural elements previously proposed as important for the biological act ivity of chromium.
