The molecular structure comprises two Zn\n                    <jats:sup>II<\/jats:sup>\n                    units.

For one of the units, two Zn\n                    <jats:sup>II<\/jats:sup>\n                    ions are bridged by\n                    <jats:italic>gauche<\/jats:italic>\n                    -bix ligands, providing a dinuclear [Zn\n                    <jats:sub>2<\/jats:sub>\n                    (2,6-PDC)\n                    <jats:sub>2<\/jats:sub>\n                    (bix)\n                    <jats:sub>2<\/jats:sub>\n                    ] macrocycle.

Interestingly, these two entities are interweaved, leading to a polyrotaxane structure extending parallel to [101]. The crystal structure is consolidated by hydrogen-bonding, \u03c0\u2013\u03c0 and C\u2014H...\u03c0 intermolecular interactions.\n                  <\/jats:p>","DOI":"10.1107\/s2056989025004608","type":"journal-article","created":{"date-parts":[[2025,5,27]],"date-time":"2025-05-27T05:35:13Z","timestamp":1748324113000},"page":"559-564","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":0,"title":["Crystal structure and characterization of a new chain-like polyrotaxane zinc(II) coordination polymer with mixed pyridine-2,6-dicarboxylate and 1,4-bis(1\n                    <i>H<\/i>\n                    -imidazol-1-ylmethyl)benzene ligands"],"prefix":"10.1107","volume":"81","author":[{"given":"Chanikarn","family":"Kummuang","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/002yp7f20","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1486-9164","authenticated-orcid":true,"given":"Kittipong","family":"Chainok","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/002yp7f20","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6232-6119","authenticated-orcid":true,"given":"Nanthawat","family":"Wannarit","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/002yp7f20","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"329","published-online":{"date-parts":[[2025,5,30]]},"reference":[{"key":"wm5758_bb1","doi-asserted-by":"crossref","first-page":"11233","DOI":"10.1039\/C6DT01157H","volume":"45","author":"Adarsh","year":"2016","journal-title":"Dalton Trans."},{"key":"wm5758_bb2","doi-asserted-by":"crossref","first-page":"1349","DOI":"10.1039\/DT9840001349","author":"Addison","year":"1984","journal-title":"J.
