The Cu<jats:sup>II<\/jats:sup> atom exhibits a distorted CuO<jats:sub>2<\/jats:sub>NCl<jats:sub>3<\/jats:sub> octahedral geometry, coordinating two oxygen atoms and one nitrogen atom from the tridentate H<jats:sub>2<\/jats:sub>pydc ligand and three chloride atoms; the nitrogen atom and one chloride atom occupy the axial positions with Cu\u2014N and Cu\u2014Cl bond lengths of 2.011\u2005(2)\u2005\u00c5 and 2.2067\u2005(9)\u2005\u00c5, respectively. In the equatorial plane, the oxygen and chloride atoms are arranged in a <jats:italic>cis<\/jats:italic> configuration, with Cu\u2014O bond lengths of 2.366\u2005(2) and 2.424\u2005(2)\u2005\u00c5, and Cu\u2014Cl bond lengths of 2.4190\u2005(10) and 2.3688\u2005(11)\u2005\u00c5. The asymmetric unit contains 8-HQ<jats:sup>+<\/jats:sup> as a counter-ion and two uncoordinated water molecules. The crystal structure features strong O\u2014H...O and O\u2014H...Cl hydrogen bonds as well as weak interactions including C\u2014H...O, C\u2014H...Cl, Cu\u2014Cl...\u03c0, and \u03c0\u2013\u03c0, which result in a three-dimensional network. A Hirshfeld surface analysis indicates that the most important contributions to the crystal packing involving the main residues are from H...Cl\/Cl...H interactions, contributing 40.3% for the anion. Weak H...H contacts contribute 13.2% for the cation and 28.6% for the anion.<\/jats:p>","DOI":"10.1107\/s2056989024009186","type":"journal-article","created":{"date-parts":[[2024,9,24]],"date-time":"2024-09-24T07:27:27Z","timestamp":1727162847000},"page":"1049-1053","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":3,"title":["8-Hydroxyquinolinium trichlorido(pyridine-2,6-dicarboxylic acid-\u03ba<sup>3<\/sup>\n                  <i>O<\/i>,<i>N<\/i>,<i>O<\/i>\u2032)copper(II) dihydrate"],"prefix":"10.1107","volume":"80","author":[{"given":"Yusufjon Eshkobilovich","family":"Nazarov","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khayit Khudainazarovich","family":"Turaev","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jabbor Ruziboevich","family":"Suyunov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bekmurod Khurramovich","family":"Alimnazarov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-3905-5556","authenticated-orcid":true,"given":"Abdusamat Abdujabborovich","family":"Rasulov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bakhtiyar Tulyaganovich","family":"Ibragimov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4441-2803","authenticated-orcid":true,"given":"Jamshid Mengnorovich","family":"Ashurov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"329","published-online":{"date-parts":[[2024,9,24]]},"reference":[{"key":"ej2008_bb1","doi-asserted-by":"crossref","first-page":"184","DOI":"10.1007\/BF03246111","volume":"5","author":"Aghabozorg","year":"2008","journal-title":"J.
