Having established the thermodynamical and mechanical characteristics of the modified ZIF glasses, we next investigate their structural features. Notably, two previous studies have solved the singlecrystal structure of a bis(imidazole)zinc(II) chloride phase, revealing a mixed linker structure, where each tetrahedral Zn is coordinating two imidazoles and two chloride anions showed that these can be melt-quenched into glasses with Tg values around 80°C . In the following, we demonstrate that the present co-melted ZIF-modifier systems adopt largely similar local configurations, where the Zn nodes coordinate to a mixture of halide anions and imidazolate linkers.
