Structures of copper(II) 2-chlorobenzoate monohydrate and copper(II) 3,5-dichlorobenzoate trihydrate

Abstract

The crystal structures of the title compounds, [Cu 2 (µ2-2-Clbz) 4 cations are bridged through four 2-chlorobenzoate ligands. The Cu 2+ 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 Cu 2+ 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.

Synthesis and structural features of copper(II) complexes of N,N,N′,N′-tetramethylethylenediamine with 2-chlorobenzoate1− and 2-hydroxybenzoate1−

“…Metal-chlorobenzoates have garnered reasonable interest not only due to their biological [17], and magnetic properties [18], but also as important constituents, in the design of new metalorganic frameworks [19][20]. The structural variety in coordination modes of their carboxylate moiety and possibility of varying nuclearities, leads to the formation of monomeric to polymeric [19] complexes.…”
