Abstract:

A novel calcium(Ⅱ) metal-organic framework [Ca2(HCOO)2(nds)(H2O)2]n(1) with mixed 1,5-naphthalene-disulfonate sodium salt(1,5-nds) and formate as organic ligands has been obtained under solvothermal conditions. It was found that the μ3-η2:η2 bridging mode of HCOO- in compound 1 is uncommon. Moreover, the formate, which was in situ formed from N,N'-dimethylformamide, played an important role in the formation of 3D structure. HCOO- ligands bridged Ca(Ⅱ) ions into grid-like layers that were further pillared by the 1,5-nds ligand to form a 3D Ca-based framework. Compound 1 also exhibits a strong blue luminescence at room temperature.
