Abstract
A novel 3D metal-organic framework based on tetranuclear copper Secondary Building Units, [Cu2(μ3-OH)(4-oip)(DMF)]·DMF·2H2O (JUC-76) (4-oip = 4-hydroxyisophthalic, DMF =N,N-dimethylformamide, and JUC = Jilin University China), has been synthesized under solvothermal conditions. It crystallizes in monoclinic symmetry with space groupP21/n. JUC-76 possesses a three-dimensional network with one-dimensional rhombic channels of approximately 13.6 × 8.5 Å2along the [100] direction. The resulting structure of JUC-76 is a distorted rutile topology with one 3-connected organic node and one 6-connected inorganic node. And its Schläfli symbol is (4·62)2(42·610·83). In addition, JUC-76 exhibits fluorescence emission at 446 nm, and a dominant anti-ferromagnetic interaction between the Cu (II) ions.
