Combining the favorable hard\u2013hard Bi-O interactions and chelating chemistry of hydroxamate groups, a rigid and symmetrical three-dimensional bismuth-hydroxamate metal\u2013organic framework was successfully prepared via solvothermal synthesis and structurally elucidated via X-ray crystallography. The MOF, namely SUM-91 (SUM = Sichuan University Materials), features one-dimensional Bi-oxo secondary building blocks (SBUs), which are bridged by chelating 1,4-benzenedihydroxamate linkers. With the demonstrated permanent porosity and molecular sieving effect (CO2 vs. N2), SUM-91 was also found to be stable under harsh chemical conditions (aqueous solutions with pH = 2\u201312 and various organic solvents). As the structural robustness of SUM-91 could be attributed to the finetuning of the coordinative sphere of Bi centers, this work shed light on the further development of (ultra-)microporous materials with high stability and selective adsorption properties.<\/jats:p>","DOI":"10.3390\/sym17060895","type":"journal-article","created":{"date-parts":[[2025,6,6]],"date-time":"2025-06-06T09:02:03Z","timestamp":1749200523000},"page":"895","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Construction of a Symmetrical Bi-Hydroxamate Metal\u2013Organic Framework with Chemical Robustness"],"prefix":"10.3390","volume":"17","author":[{"given":"Yue","family":"Dong","sequence":"first","affiliation":[{"name":"School of Chemical Engineering, Sichuan University, Chengdu 610065, China"}]},{"given":"Chaozhi","family":"Xiong","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Sichuan University, Chengdu 610065, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1168-014X","authenticated-orcid":false,"given":"Zhen-Wu","family":"Shao","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Sichuan University, Chengdu 610065, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9780-9062","authenticated-orcid":false,"given":"Chong","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Sichuan University, Chengdu 610065, China"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"213655","DOI":"10.1016\/j.ccr.2020.213655","article-title":"Applications of reticular diversity in metal\u2013organic frameworks: An ever-evolving state of the art","volume":"430","author":"Ejsmont","year":"2021","journal-title":"Coord.
