Popis:	Chemical communications 58, 11949 - 11952 (2022). doi:10.1039/D2CC04241J The structure of a new ZIF-8 polymorph with quartz topology (qtz) is reported. This qtz-[Zn(mIm)$_2$] phase was obtained by mechanically amorphising crystalline ZIF-8, before heating the resultant amorphous phase to between 282 and 316 °C. The high-temperature phase structure was obtained from powder X-ray diffraction, and its thermal behaviour, CO$_2$ gas sorption properties and dye adsorption ability were investigated.
