Abstract: The crystal structures of the title compounds, [Cu2(µ2-2-Clbz)4(H2O)2] (1) and [Cu(3,5-Cl2bz)2(H2O)3] (2), have been redetermined at 150 K. The compound 1 forms dimeric complex where two Cu2+ cations are bridged through four 2-chlorobenzoate ligands. The Cu2+ ion in 1 is pentacoordinated by four oxygen atoms of bridging 2-chlorobenzoate ligands and one coordinated water molecule. The compound 2 forms mononuclear complex, where the Cu2+ ion is pentacoordinated by two oxygen atoms of monodentate 3,5-dichlorobenzoate ligands and three coordinated water molecule. Both complexes are connected through O—H···O hydrogen bonds into frameworks. The π-π stacking interactions are also observed in crystal structure of 2.

Keywords: copper, X-ray, chlorobenzoate, dichlorobenzoate, hydrogen bonds
