An interpenetrated framework based on pentanuclear tetrahedral cluster with four-connected mdf network

A new three-dimensional metal–organic framework constructed form pentanuclear tetrahedral cluster and linear dicarboxylic acid ligand, [Zn5(btz)6(ndc)2(H2O)]·3DMA (1) (btz = benzotriazole, H2ndc = 1,4-naphthalenedicarboxylic acid) has been synthesized by the modular building blocks (MBBs) strategy under the solvothermal condition. Single X-ray diffraction reveals that 1 is a two-fold interpenetrated framework with mdf topology, in which pentanuclear {Zn5(btz)6} cluster acts as a 4-connected node. Moreover, the luminescent properties of 1 dispersed in different metal ions and solvents have been investigated systematically.
