摘要
A novel calcium(Ⅱ) metal-organic framework [Ca2(HCOO)2(nds)(H2O)2]n(1) with mixed 1,5-naphthalenedisulfonate sodium salt(1,5-nds) and formate as organic ligands has been obtained under solvothermal conditions.It was found that theμ3-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.
