X-ray studies have revealed that the basic building block in 1, 3, and 4 is comprised of two copper centers bridged through one \u03bc-phenolate oxygen atom from HL2\u2212 or H3L12\u2212, and one \u03bc-1,1-azido (N3\u2212) ion and in 2, 5, and 6 by \u03bc-phenoxide oxygen of L3\u2212 or H3L12\u2212 and \u03bc-O2\u2212 or \u03bc3-O2\u2212 ions. H-bonding involving coordinated\/uncoordinated hydroxy groups of the ligands generates fascinating supramolecular architectures with 1D-single chains (1 and 6), 2D-sheets (3), and 3D-structures (4). In 5, benzoate ions display four different coordination modes, which, in our opinion, is unprecedented and constitutes a new discovery. In 1, 3, and 5, Cu(II) ions in [Cu2] units are antiferromagnetically coupled, with J ranging from \u2212177 to \u2212278 cm\u22121.<\/jats:p>","DOI":"10.3390\/molecules25235549","type":"journal-article","created":{"date-parts":[[2020,11,26]],"date-time":"2020-11-26T22:00:33Z","timestamp":1606428033000},"page":"5549","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Self-Assembly of Antiferromagnetically-Coupled Copper(II) Supramolecular Architectures with Diverse Structural Complexities"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0992-4392","authenticated-orcid":false,"given":"Santokh S.","family":"Tandon","sequence":"first","affiliation":[{"name":"Department of Chemistry and Biochemistry, Kent State University-Salem Campus, Salem, OH 44460, USA"},{"name":"Department of Chemistry and Biochemistry, Kent State University, Kent, OH 44242, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Scott D.","family":"Bunge","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Biochemistry, Kent State University, Kent, OH 44242, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Neil","family":"Patel","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Biochemistry, Kent State University, Kent, OH 44242, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Esther C.","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Biochemistry, Kent State University, Kent, OH 44242, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laurence K.","family":"Thompson","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Memorial University, St. John\u2019s Newfoundland, NL A1B 3X7, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2817","DOI":"10.1039\/b820283b","article-title":"Combining supramolecular chemistry with biology","volume":"39","author":"Uhlenheuer","year":"2010","journal-title":"Chem.
