Two solvent and temperature dependent copper(II) compounds formed by a flexible ligand: syntheses, structures and SC–SC transformation

Abstract

A nonporous neutral framework [CuCl2(m-bttmb)2]n (1) was changed into a porous ionic {[Cu(m-bttmb)2(H2O)Cl]Cl(CH3CN)0.5(H2O)2.75}n (2) by simply increasing the amount of CH3CN in the mixed solvent (CH3CN and H2O) or temperature in the reactions of CuCl2·2H2O with 1,3-bis(triazol-1-ylmethyl)-2,4,6-trimethylbenzene (m-bttmb). 1 undergoes transformation into 2 when treated with CH3CN. Both 1 and 2 have 2D 4-connected (4,4) network architectures but in different packing arrangements. These compounds have been characterized by single-crystal X-ray diffraction analysis, elemental analysis, IR spectra and thermogravimetric analysis. This work may provide a way to control the formation of neutral or ionic frameworks, as well as porosities by adjusting the polarity and components of the solvents.
