In Situ Tetrazole Ligand Synthesis of Two‐Fold Interpenetrating Zinc Coordination Frameworks

Four d10 metal directed coordination frameworks, [Zn2(MT)3(IN)] (1; MT = 5‐methyltetrazole, IN = isonicotinic acid), [Zn(ET)(IN)] (2; ET = 5‐ethyltetrazole), [Zn(PT)2] (3; PT = 5‐propyltetrazole), and [Zn(IPT)2] (4; IPT = 5‐isopropyltetrazole), have been obtained by in situ tetrazole synthesis and structurally characterized by elemental analyses, FTIR spectroscopy, and thermal studies, as well as by single‐crystal and powder X‐ray diffraction analyses. Compound 1 exhibits a two‐fold diamondoid network constructed of two‐dimensional (2D) Zn–MT wheel layers and IN linkers. Compound 2 displays a similar two‐fold diamondoid network constructed by interconnection of Zn–ET–IN honeycomb layers and IN ligands. Compound 3 represents a 3D coordination polymer constructed from numerous Zn6(PT)6 wheels with a diamondoid net. Compound 4 is a 2D network constructed by the self‐assembly of Zn ions and IPT ligands with an sql net. Furthermore, the solid‐state properties of these crystalline materials, such as their thermal behavior and photoluminescence properties, have also been investigated.
