Di-μ-benzoato-κ³O,O′:O′;κ³O:O,O′-bis[aquabis(benzoato-κ²O,O′)(dimethylformamide-κO)europium(III)]

Abstract

The title dimeric complex, [Eu2(C7H5O2)6(C3H7NO)2(H2O)2], is centrosymmetric, implying that pairs of equivalent Eu3+ ions and ligands lie trans to each other and that the two Eu3+ ions have exactly the same coordination environment. Each Eu3+ ion is nine-coordinated by two bidentate benzoate ligands, two bridging tridentate chelating benzoate ligands, and one dimethylformamide and one water molecule. The coordination polyhedron of each Eu3+ ion can be described with a distorted monocapped square-anti­prismatic geometry. The mol­ecular structure is stabilized by intra- and inter­molecular hydrogen bonds between the water mol­ecules and benzoate O atoms.
