Weak antiferromagnetic interactions in hydronium diaqua-1kappaO,2kappaO-trichloro-1kappaCl,2kappa2Cl-mu-dimethylglycinato-1kappaO:2kappa2O',N-dimethylglycinato-1kappa2N,O-dicuprate(II).

The crystal structure of the title compound, (H3O)[Cu2(C4H8NO2)2Cl3(H2O)2], contains two Cu(II) ions bridged by the carboxylate group of a dimethylglycinate ion in an anti-anti configuration. The Cu(II) atoms both have an approximately square-pyramidal conformation geometry and are 5.977 (2) angstroms apart. The two dimethylglycinate ligands have similar conformations, although they play different roles in the structure. A weak antiferromagnetic interaction between the two copper ions could be inferred from the magnetic susceptibility measurements.
