In this work, we performed a synthetic screening aimed at synthesizing this hypothetical MOF, which failed to afford the desired product and led to the discovery of two new nonporous coordination polymers, named UdP-40 and UdP-41, with the same 2:2:1 Zn\/1,2,4-triazolate\/squarate stoichiometry expected for a CALF-20 analogue, but different crystal structure. UdP-40 and UdP-41 were characterized by elemental analysis, thermogravimetric analysis, variable temperature powder X-ray diffraction,infrared spectroscopy and CO2 sorption analysis, and their structures were solved from powder and single crystal X-ray diffraction, respectively. Both compounds crystallize in orthorhombic space groups and display the same peculiar tetradentate coordination mode for squarate, involving two monodentate O atoms and one bridging O atom, while leaving one free O atom, leading to the formation of previously unreported topologies. UdP-40 features one coordinated water molecule per formula unit, whose removal at temperatures above 250 \u00b0C leads to complete amorphization.<\/jats:p>","DOI":"10.1021\/acs.cgd.6c00193","type":"journal-article","created":{"date-parts":[[2026,8,6]],"date-time":"2026-08-06T17:01:56Z","timestamp":1786035716000},"page":"6310-6318","source":"Crossref","is-referenced-by-count":0,"title":["Squarate-Based Isoreticular\nAnalogue of CALF-20: Fact\nor Fiction?"],"prefix":"10.1021","volume":"26","author":[{"given":"Francesco","family":"Della Croce","sequence":"first","affiliation":[{"name":"University of Pisa , , Via G.
