When the same reaction was performed in a mixture of ethanol and water as solvent, a few crystals of [ZnI\n 2<\/jats:sub>\n (C\n 6<\/jats:sub>\n H\n 8<\/jats:sub>\n N\n 2<\/jats:sub>\n )(H\n 2<\/jats:sub>\n O)]\u00b70.5C\n 6<\/jats:sub>\n H\n 8<\/jats:sub>\n N\n 2<\/jats:sub>\n \u00b70.5H\n 2<\/jats:sub>\n O (\n 2<\/jats:bold>\n ) were serendipitiously obtained in a mixture with compound\n 1<\/jats:bold>\n as the major phase. The asymmetric unit of\n 1<\/jats:bold>\n consists of one zinc cation, two crystallographically independent iodide anions and one 2,3-dimethylpyrazine ligand all of them located in general positions. In the extended structure, the Zn cations are tetrahedrally coordinated by two iodide anions and two symmetry-related 2,3-dimethylpyrazine ligands and are linked by bridging 2,3-dimethylpyrazine ligands into helical chains that proceed along the\n c<\/jats:italic>\n -axis direction in the uncommon space group\n P<\/jats:italic>\n 3\n 2<\/jats:sub>\n . Within these chains, intrachain C\u2014H...I hydrogen bonding is observed. The asymmetric unit of\n 2<\/jats:bold>\n consists of two crystallographically independent [ZnI\n 2<\/jats:sub>\n (C\n 6<\/jats:sub>\n H\n 8<\/jats:sub>\n N\n 2<\/jats:sub>\n )(H\n 2<\/jats:sub>\n O)] complexes as well as one water molecule and one none-coordinating 2,3-dimethylpyrazine ligand. In the complexes, the Zn cations are tetrahedrally coordinated by two iodide anions, one 2,3-dimethylpyrazine ligand and one water molecule. These complexes are packed in such a way that cavities are formed, which are filled by water and 2,3-dimethylpyrazine solvate molecules that are hydrogen bonded to each other.\n <\/jats:p>","DOI":"10.1107\/s2056989026001088","type":"journal-article","created":{"date-parts":[[2026,2,3]],"date-time":"2026-02-03T06:39:21Z","timestamp":1770100761000},"page":"244-248","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":3,"title":["Syntheses and crystal structures of\n catena<\/i>\n -poly[[diiodidozinc(II)]-\u03bc-2,3-dimethylpyrazine-\u03ba\n 2<\/sup>\n N<\/i>\n 1<\/sup>\n :\n N<\/i>\n 4<\/sup>\n ] and aqua(2,3-dimethylpyrazine-\u03ba\n N<\/i>\n )diiodidozinc(II)\u20132,3-dimethylpyrazine\u2013water (2\/1\/1)"],"prefix":"10.1107","volume":"82","author":[{"given":"Christian","family":"N\u00e4ther","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gaurav","family":"Bhosekar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"329","published-online":{"date-parts":[[2026,2,3]]},"container-title":["Acta Crystallographica Section E Crystallographic Communications"],"original-title":[],"link":[{"URL":"https:\/\/journals.iucr.org\/e\/issues\/2026\/03\/00\/hb8191\/hb8191.pdf","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.iucr.org\/e\/issues\/2026\/03\/00\/hb8191\/hb8191.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,5]],"date-time":"2026-03-05T11:19:07Z","timestamp":1772709547000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.iucr.org\/paper?S2056989026001088"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,2,3]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2026,3]]}},"alternative-id":["S2056989026001088"],"URL":"https:\/\/doi.org\/10.1107\/s2056989026001088","relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.1107\/S2056989026001088\/hb8191sup1.cif","asserted-by":"subject"},{"id-type":"doi","id":"10.1107\/S2056989026001088\/hb81911sup2.hkl","asserted-by":"subject"},{"id-type":"doi","id":"10.1107\/S2056989026001088\/hb81912sup3.hkl","asserted-by":"subject"}]},"ISSN":["2056-9890"],"issn-type":[{"value":"2056-9890","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,2,3]]},"assertion":[{"value":"Acta Crystallographica Section E: Crystallographic Communications","order":0,"name":"journal","label":"Publication","explanation":{"URL":"https:\/\/journals.iucr.org\/e"},"group":{"name":"general","label":"General"}},{"value":"research communications","order":1,"name":"content_type","label":"Content type","explanation":{"URL":"https:\/\/journals.iucr.org\/e\/services\/notesforauthors.html"},"group":{"name":"general","label":"General"}},{"value":"Available","URL":"https:\/\/scripts.iucr.org\/cgi-bin\/citedin?hb8191","order":2,"name":"article_metrics","label":"Article metrics","group":{"name":"general","label":"General"}},{"value":"Yes","order":0,"name":"peer_reviewed","label":"Peer reviewed","group":{"name":"peer_review","label":"Peer review"}},{"value":"Single blind","order":1,"name":"review_process","label":"Review process","group":{"name":"peer_review","label":"Peer review"}},{"value":"23 January 2026","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication history"}},{"value":"2 February 2026","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication history"}},{"value":"3 February 2026","order":2,"name":"published_online","label":"Published online","group":{"name":"publication_history","label":"Publication history"}},{"value":"This article has supporting information","name":"supplementary_materials","label":"Supplementary materials","explanation":{"URL":"https:\/\/scripts.iucr.org\/cgi-bin\/sendsup?hb8191"}},{"value":"\u00a9 2026 N\u00e4ther and Bhosekar","order":0,"name":"copyright","label":"Copyright","explanation":{"URL":"https:\/\/journals.iucr.org\/services\/copyrightpolicy.html"},"group":{"name":"copyright_and_licencing","label":"Copyright and licencing"}},{"value":"Creative Commons Attribution (CC-BY)","order":1,"name":"license","label":"Licence","explanation":{"URL":"https:\/\/creativecommons.org\/licenses\/by\/4.0\/legalcode"},"group":{"name":"copyright_and_licencing","label":"Copyright and licencing"}}]}}
