Their synthesis required hydrothermal conditions, causing the partial in situ transformation of 5-fluoro uracil-1-acetic acid (5-FUA) into an oxalate ion (ox), as well as the protonation of the 4,4\u2032-bipyridine (bipy) ligand through a catalytic process resulting from the presence of Cu(II) within the reaction. These initial conditions allowed obtaining the new coordination compounds [Cu2(5-FUA)2(ox)(bipy)]n\u00b72n H2O\u00a0(CP2),\u00a0[Cu(5-FUA)2(H2O)(bipy)]n\u00b72n H2O (CP3), as well as the ionic pair [(H2bipy)+2 2NO3\u2212] (1). The mother liquor evolved rapidly at room temperature and atmospheric pressure, due to the change in concentration of the initial reagents and the presence of the new chemical species generated in the reaction process, yielding CPs [Cu(5-FUA)2(bipy)]n\u00b73.5n H2O, [Cu3(ox)3(bipy)4]n and [Cu(ox)(bipy)]n. The molecular compound [Cu(5-FUA)2(H2O)4]\u00b74H2O (more thermodynamically stable) ended up in the mother liquor after filtration at longer reaction times at 25 \u00b0C and 1 atm., cohabiting in the medium with the other crystalline solids in different proportions. In addition, the evaporation of H2O caused the single-crystal to single-crystal transformation (SCSC) of [Cu(5-FUA)2(H2O)(bipy)]n\u00b72n H2O (CP3) into [Cu(5-FUA)2(bipy)]n\u00b72n H2O (CP4). A theoretical study was performed to analyze the thermodynamic stability of the phases. The observed SCSC transformation also involved a perceptible color change, highlighting this compound as a possible water sensor.<\/jats:p>","DOI":"10.3390\/polym15132827","type":"journal-article","created":{"date-parts":[[2023,6,27]],"date-time":"2023-06-27T01:49:21Z","timestamp":1687830561000},"page":"2827","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Structural and Theoretical Study of Copper(II)-5-fluoro Uracil Acetate Coordination Compounds: Single-Crystal to Single-Crystal Transformation as Possible Humidity Sensor"],"prefix":"10.3390","volume":"15","author":[{"given":"Ver\u00f3nica G.","family":"Vegas","sequence":"first","affiliation":[{"name":"Departamento de Qu\u00edmica Inorg\u00e1nica, Facultad de Ciencias, Universidad Aut\u00f3noma de Madrid, 28049 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9584-4964","authenticated-orcid":false,"given":"Andrea","family":"Garc\u00eda-Hern\u00e1n","sequence":"additional","affiliation":[{"name":"Departamento de Qu\u00edmica Inorg\u00e1nica, Facultad de Ciencias, Universidad Aut\u00f3noma de Madrid, 28049 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2751-5592","authenticated-orcid":false,"given":"Fernando","family":"Aguilar-Galindo","sequence":"additional","affiliation":[{"name":"Departamento de Qu\u00edmica, Facultad de Ciencias, Universidad Aut\u00f3noma de Madrid, 28049 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0256-0186","authenticated-orcid":false,"given":"Josefina","family":"Perles","sequence":"additional","affiliation":[{"name":"Laboratorio de DRX Monocristal, Servicio Interdepartamental de Investigaci\u00f3n, Universidad Aut\u00f3noma de Madrid, 28049 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1952-1020","authenticated-orcid":false,"given":"Pilar","family":"Amo-Ochoa","sequence":"additional","affiliation":[{"name":"Departamento de Qu\u00edmica Inorg\u00e1nica, Facultad de Ciencias, Universidad Aut\u00f3noma de Madrid, 28049 Madrid, Spain"},{"name":"Institute for Advanced Research in Chemical Sciences (IAdChem), Universidad Aut\u00f3noma de Madrid, 28049 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,26]]},"reference":[{"key":"ref_1","unstructured":"Batten, S.R.N., Neville, S.M., and Turner, D.
