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 CrIII ion is in a distorted octahedral environment and coordinated by one nitrogen and three carboxylate O atoms of the nta3- 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 nta3- 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.
