Abstract

The crystal structure of the title compound, K₂[Cr ₂(C₆H₆NO₆)₂(OH) ₂]·6H₂O or K₂[Cr₂(μ-OH) ₂(nta)₂]-6H₂O (nta = nitrilotriacetate), is composed of a dinuclear hydroxo-bridged chromium(III) complex anion, potassium cation and water molecules. Each Cr^III ion is in a distorted octahedral environment and coordinated by one nitrogen and three carboxylate O atoms of the nta^3- ligand plus two bridging hydroxo O atoms. The dinuclear complex anion possesses 2/m crystallographic symmetry. The Cr-O(μ-OH) bond lengths are 1.937 (4) and 1.951 (4) Å. The Cr-N and Cr-O bond distances of the nta^3- ligand are 2.054 (4) and 1.968(3)-1.983 (3) Å, while the HO-Cr-OH and Cr-OH-Cr angles are 80.46 (16) and 99.54 (16)°, respectively.
