MOFs emerged as an explicit subfield of chemistry in the late 1980s and 1990s. However, much foundational work was accomplished in earlier decades. Here, we detail the structural and gas-adsorption characterization of [Cu(im)\n                    <jats:sub>2<\/jats:sub>\n                    ] (im = imidazolate), a ZIF that was widely reported in the early 1960s. This compound exists as several polymorphs. We re-prepared the historic blue polymorph [Cu(im)\n                    <jats:sub>2<\/jats:sub>\n                    ]-B, which has a sodalite topology, confirmed its identity by single-crystal X-ray diffraction, and measured its gas-adsorption isotherms. We conclude that the true origin of ZIFs lies with a copper(II) framework discovered more than 60 years ago that has been overlooked by recent literature.\n                  <\/jats:p>","DOI":"10.1107\/s2052252526008912","type":"journal-article","created":{"date-parts":[[2026,10,20]],"date-time":"2026-10-20T14:47:54Z","timestamp":1792507674000},"update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":0,"title":["The overlooked ZIF: reviving [Cu(imidazolato)\n                    <sub>2<\/sub>\n                    ] from 1960s literature"],"prefix":"10.1107","volume":"13","author":[{"given":"Cara","family":"Bosman","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/052czxv31","id-type":"ROR","asserted-by":"publisher"}],"department":["MacDiarmid Institute for Advanced Materials and Nanotechnology, School of Food Technology and Natural Sciences"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shane G.","family":"Telfer","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/052czxv31","id-type":"ROR","asserted-by":"publisher"}],"department":["MacDiarmid Institute for Advanced Materials and Nanotechnology, School of Food Technology and Natural Sciences"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"329","published-online":{"date-parts":[[2026,10,20]]},"container-title":["IUCrJ"],"original-title":[],"link":[{"URL":"https:\/\/journals.iucr.org\/m\/issues\/2026\/06\/00\/kin5001\/kin5001.pdf","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.iucr.org\/m\/issues\/2026\/06\/00\/kin5001\/kin5001.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,22]],"date-time":"2026-10-22T15:36:14Z","timestamp":1792683374000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.iucr.org\/paper?S2052252526008912"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,10,20]]},"references-count":0,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2026,11]]}},"alternative-id":["S2052252526008912"],"URL":"https:\/\/doi.org\/10.1107\/s2052252526008912","relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.1107\/S2052252526008912\/kin5001sup1.cif","asserted-by":"subject"}]},"ISSN":["2052-2525"],"issn-type":[{"value":"2052-2525","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,10,20]]},"assertion":[{"value":"IUCrJ","order":0,"name":"journal","label":"Publication","explanation":{"URL":"https:\/\/www.iucrj.org\/"},"group":{"name":"general","label":"General"}},{"value":"research papers","order":1,"name":"content_type","label":"Content type","explanation":{"URL":"https:\/\/journals.iucr.org\/m\/services\/notesforauthors.html"},"group":{"name":"general","label":"General"}},{"value":"Available","URL":"https:\/\/scripts.iucr.org\/cgi-bin\/citedin?kin5001","order":2,"name":"article_metrics","label":"Article metrics","group":{"name":"general","label":"General"}},{"value":"Yes","order":0,"name":"peer_reviewed","label":"Peer reviewed","group":{"name":"peer_review","label":"Peer review"}},{"value":"Single blind","order":1,"name":"review_process","label":"Review process","group":{"name":"peer_review","label":"Peer review"}},{"value":"4 June 2026","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication history"}},{"value":"26 August 2026","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication history"}},{"value":"20 October 2026","order":2,"name":"published_online","label":"Published online","group":{"name":"publication_history","label":"Publication history"}},{"value":"This article has supporting information","name":"supplementary_materials","label":"Supplementary materials","explanation":{"URL":"https:\/\/scripts.iucr.org\/cgi-bin\/sendsup?kin5001"}},{"value":"\u00a9 2026 Bosman and Telfer","order":0,"name":"copyright","label":"Copyright","explanation":{"URL":"https:\/\/journals.iucr.org\/services\/copyrightpolicy.html"},"group":{"name":"copyright_and_licencing","label":"Copyright and licencing"}},{"value":"Creative Commons Attribution (CC-BY)","order":1,"name":"license","label":"Licence","explanation":{"URL":"https:\/\/creativecommons.org\/licenses\/by\/4.0\/legalcode"},"group":{"name":"copyright_and_licencing","label":"Copyright and licencing"}}]}}
