A novel 3D (3,5)-connected metal–organic framework based on a flexible hexacarboxylate

A novel three-dimensional (3D) metal-organic framework, [Cd2(HL)(H2O)2]·H3O·0.25(imi) 1, (H6L = 5,5′,5″-(2,4,6-trimethylbenzene-1,3,5-triyl)trismethylene-trisoxy-triisophthalic acid and imi = imidazole) has been prepared under hydrothermal condition. Compound 1 possesses a 3D (3,5)-connected framework with (52·8)(5·6·8)(6·82)(52·6·85·9·10) topology. The thermogravimetric and luminescent properties have also been studied for the compound.
