In the crystal structure of the title complex, [Cr3(CH3CO2)6(N3)O(CH3OH)2]·CH3OH, the trinuclear core has a central O atom; two methanol molecules and an azide ion are coordinated to the CrIII atoms in the core. The three CrIII atoms form vertices of a nearly equilateral triangle. Each of the six acetate carboxylate groups bridges a Cr—O—Cr fragment. In the crystal, the molecules interact with methanol solvent molecules through O—H...O and O—H...N hydrogen bonds, forming a two-dimensional hydrogen-bonded network parallel to (100).
