Description:
The assembly reactions between a rigid imidazole/carboxylate functionalized ligand, 2-(5, 7-dioxopyrrolo[3, 4-f]benzimidazole-6-yl)benzoic acid (H 2 2-DPBB) and Mg 2+ (Li + ) ions led to the formation of two 2D layered compounds, [Mg(H2-DPBB) 2 (DMF) 2 ] ( 1 ) and [Li(H2-DPBB)(DMF)] ( 2 ) (DMF = N , N -dimethylformamide). Single crystal structural analyses show that compound 1 has a 2D (4, 4)-net structure based on 4-connected mononuclear Mg 2+ nodes and HDPBB spacers. Compound 2 also has a 2D (4, 4)-net structure but based on dinuclear {Li 2 } nodes and HDPBB spacers. Interesting hydrogen bond and π–π interactions are observed in the structures. Additionally, the IR spectra and thermal behaviors of 1 and 2 are presented.
