Crystal Structure of a Copper–mefenamate Complex Solvated with Diglyme and Water

In the copper–mefenamate complex tetrakis[μ-2-(2,3-dimethylanilino)benzoato-κ2 O:O′]bis[aquacopper(II)]–1-methoxy-2-(2-methoxyethoxy)ethane (1/2), [Cu2(C15H14NO2)4(H2O)2]·2C6H14O3, the asymmetric unit comprises a CuII cation coordinated to two mefenamate ligands solvated with a water molecule and a diglyme molecule. The complex adopts a paddlewheel motif and is compared to structural analogues crystallized with dimethylformamide and dimethyl sulfoxide.
