Cationic Cd(II) metal − organic framework based on tetrakis(1,2,4-triazol-1-yl)methane

Abstract

Solvothermal reaction of a multidentate ligand (tetrakis[4-(1-triazolyl)phenyl]-methane (ttpm)), with Cd(NO₃)₂ afforded a cationic Cd(II) coordination polymer {[Cd(ttpm)·DMSO]·2NO₃}_n. Single-crystal X-ray diffraction analyses showed that ttpm belonged to the tetragonal space group I4₁/a, and 1 was a 2-D (4,4) network. 1-D channels along the c direction exist in the 3D stacking map to accommodate the charge-balancing NO₃⁻ anions. N₂ adsorption/desorption experiments showed the framework had a BET surface area of 11.36 m²·g⁻¹. Compared with luminescence of ttpm, 1 showed red-shifted luminescence spectra with higher intensity from the more rigid arrangement of the π systems.
