In five of the structures (\n 1<\/jats:bold>\n \u2013\n 5<\/jats:bold>\n ), the CuCN network includes Cu atoms occurring in pairs, linked by cuprophilic interactions. Analysis with the intent of exploring the `template effect' of the cations on the CuCN network structure indicated five separate CuCN topologies. The two different crystal structures involving cations from\n N<\/jats:italic>\n -ethylethanolamine have the same basic topology, whereas the two crystal structures involving cations from\n N<\/jats:italic>\n ,\n N<\/jats:italic>\n -diisopropylethanolamine have different topologies, contrary to what might be expected from a template effect. Thermogravimetric analysis of the compounds usually shows loss of HCN(g) and the free base by 200\u2005\u00b0C, with a CuCN(s) residue, but decomposition of one of the structures is more complex.\n <\/jats:p>","DOI":"10.1107\/s2053229625008113","type":"journal-article","created":{"date-parts":[[2025,9,17]],"date-time":"2025-09-17T07:10:23Z","timestamp":1758093023000},"page":"584-595","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":0,"title":["Crystal structures and thermogravimetric analyses of six CuCN network structures with protonated\n N<\/i>\n -alkylethanolamines as guest cations"],"prefix":"10.1107","volume":"81","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9548-5850","authenticated-orcid":true,"given":"Peter W.
