| Abstract |
Treatment of zinc(II) acetate with a ditopic (bis-tridentate) thiocarbazone \H2L, bis(pyridine-2-aldehyde) thiocarbazone\ as a principal building block and potassium thiocyanate as a source of auxiliary ligand resulted in the self-assembly generation of a novel heterometallic Zn(II)/K(I) metal-organic framework (MOF) formulated as [Zn-2(L)K-2(mu(2)-H2O)(2)(mu(2)-SCN)(4)](n). (1). It was isolated as a microcrystalline solid and fully characterized, including by single crystal X-ray diffraction. Crystal structure of 1 reveals a very intricate 3D framework assembled from the [Zn2L](2+) and [K-2(mu(2)-H2O)(2)](2+) secondary building units (SBUs) and multiple mu(2)-thiocyanate linkers. Topological analysis of the simplified underlying net of 1 disclosed a binodal 4,8-connected framework with the flu (fluorite) topology. Synthesis, characterization, structural and topological features, as well as Hirshfeld surface analysis are discussed in the present study. (C) 2018 Elsevier Ltd. All rights reserved. |
