“…However, unfortunately, the crystallization process of this compound in water was not successful. In an continuation of our previous work on investigating the structural conversion of MOFs , and coordination polymers, − in this case a comparison between the PXRD pattern of the A phase with those of other reported MOFs constructed from Ca 2+ and terephthalic acid in the presence of water was done in order to find some similar patterns (Figure S8 in the Supporting Information). (1) A PXRD pattern (Figure S8 in the Supporting Information) that is attributed to a MOF with the formula [Ca(BDC)(DMF)(H 2 O)] n formula was similar to that of the A phase.…”

A new Ca-MOF with the chemical formula of [Ca(NO2-BDC)·DMF] n (MUT-1; NO2-BDC2– = 2-nitroterephthalate) with 5,5T4 topology and the Schäfli symbol of (48.62)(45.65) was synthesized and structurally characterized with FT-IR, PXRD, BET, TG-DTA, and single-crystal X-ray techniques. MUT-1 has 1D channels along the crystallographic c axis. Its 1D channels have microporosity before the activation process, and its nanoporous structure can be achieved with the activation process. 1D channels of MUT-1 are surrounded by −NO2 groups, which indicate that this MOF could be a good candidate for CO2 storage. It shows 0.97 mmol g–1 of CO2 adsorption at 298 K up to 1 bar pressure. The structural stability of MUT-1 in various solvents was investigated, and a new phase after subsequent exposure to water and DMF was characterized.
