The X-ray crystallography revealed that the chirality in complexes is centered at lanthanide(III) ions due to two vicinally located \u03bc-acetato-bridging ligands. The presented crystals have isoskeletal coordination units but they crystallize in monoclinic (1, 2) or trigonal crystal systems (3\u20135) with slightly different conformation. In 1 and 2 the ZnII\u2013LnIII\u2013ZnII coordination core is linear, whereas in isostructural crystals 3\u20135 the chiral coordination cores are bent and lie on a two-fold axis. The complexes 1, 3\u20135 show a blue emission attributed to the emission of the ligand. For ZnII2SmIII complex (2) the characteristic emission bands of f-f* transitions were observed. The magnetic properties for compounds 1, 4 and 5 are characteristic for the paramagnetism of the corresponding lanthanide(III) ions.<\/jats:p>","DOI":"10.3390\/molecules23071761","type":"journal-article","created":{"date-parts":[[2018,7,19]],"date-time":"2018-07-19T03:50:43Z","timestamp":1531972243000},"page":"1761","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Heterometallic ZnII\u2013LnIII\u2013ZnII Schiff Base Complexes with Linear or Bent Conformation\u2014Synthesis, Crystal Structures, Luminescent and Magnetic Characterization"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5765-4641","authenticated-orcid":false,"given":"Barbara","family":"Miroslaw","sequence":"first","affiliation":[{"name":"Department of Crystallography, Faculty of Chemistry, Maria Curie-Sklodowska University, 20-031 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Beata","family":"Crist\u00f3v\u00e3o","sequence":"additional","affiliation":[{"name":"Department of General and Coordination Chemistry, Faculty of Chemistry, Maria Curie-Sklodowska University, 20-031 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6077-8346","authenticated-orcid":false,"given":"Zbigniew","family":"Hnatejko","sequence":"additional","affiliation":[{"name":"Department of Rare Earths, Faculty of Chemistry, Adam Mickiewicz University, 61-614 Pozna\u0144, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,7,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"16148","DOI":"10.1039\/C6DT03392J","article-title":"Supramolecular 3d-4f Single-Molecule Magnet Architectures","volume":"45","author":"Schmitz","year":"2016","journal-title":"Dalton Trans."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"9563","DOI":"10.1021\/acs.inorgchem.7b01011","article-title":"3d\/4f Coordination Clusters as Cooperative Catalysts for Highly Diastereoselective Michael Addition Reactions","volume":"56","author":"Griffiths","year":"2017","journal-title":"Inorg.
