In this structure, copper is coordinated to four oxygen atoms from two monoanionic acetylacetonate (acac) ligands and two nitrogen atoms from two neutral L1 ligands. The transformation of complex\n                    <jats:bold>1<\/jats:bold>\n                    into complex\n                    <jats:bold>2<\/jats:bold>\n                    is achieved by heating at 80\u2009\u00b0C for 48\u2009h, leading to the removal of methanol. This elimination facilitates the formation of direct hydrogen bonds between the NH\n                    <jats:sub>2<\/jats:sub>\n                    groups and nitrogen atoms of adjacent triazine rings, establishing a network of intermolecular interactions. Structural analysis revealed a 0.2\u2009\u00c5 elongation of the copper\u2013nitrogen bond in the L1 ligand as a result of methanol removal. Complementary characterization techniques, including FTIR, UV\u2013vis spectroscopy, and Hirshfeld surface analysis, are employed to further elucidate the transformations. The impact of methanol elimination on the crystal structure is assessed, highlighting the changes in intermolecular interactions.\n                  <\/jats:p>","DOI":"10.1002\/open.202500126","type":"journal-article","created":{"date-parts":[[2025,8,13]],"date-time":"2025-08-13T10:09:44Z","timestamp":1755079784000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Single\u2010Crystal\u2010to\u2010Single\u2010Crystal Transformation in a Copper(II) Complex: Structural and Spectroscopic Insights into Methanol Elimination and Hydrogen Bond Network Formation"],"prefix":"10.1002","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9042-6288","authenticated-orcid":false,"given":"Babak","family":"Mirtamizdoust","sequence":"first","affiliation":[{"name":"Inorganic Materials and Coordination Compounds Research Lab.
