Compounds 1 and 2, formulated as Ln2(ClCNAn)3(DMSO)6 (LnIII = Tb, 1; Eu, 2), and their related intermediates 1\u2032 and 2\u2032, formulated as Ln2(ClCNAn)3(H2O)x\u00b7yH2O (x + y likely = 12, Ln = Tb, 1\u2032; and Eu, 2\u2032), were prepared by a conventional one-pot reaction (the latter) and recrystallized from DMSO solvent (the former). Polyhydrated intermediates 1\u2032 and 2\u2032 show very similar XRPD patterns, while, despite their common stoichiometry, 1 and 2 are not isostructural. Compound 1 consists of a 2D coordination framework of 3,6 topology, where [Tb(DMSO)3]III moieties are bridged by three bis-chelating ClCNAn2\u2212 ligands, forming distorted hexagons. Ultrathin nanosheets of 1 were obtained by exfoliation via the liquid-assisted sonication method and characterized by atomic force microscopy, confirming the 2D nature of 1. The crystal structure of 2, still showing the presence of 2D sheets with a \u201chexagonal\u201d mesh and a common (3,6) connectivity, is based onto flat, non-corrugated slabs. Indeed, at a larger scale, the different \u201crectangular tiles\u201d show clear roofing in 1, which is totally absent in 2. The magnetic behavior of 1 very likely indicates depopulation of the highest crystal-field levels, as expected for TbIII compounds.<\/jats:p>","DOI":"10.3390\/molecules28186453","type":"journal-article","created":{"date-parts":[[2023,9,6]],"date-time":"2023-09-06T10:23:42Z","timestamp":1693995822000},"page":"6453","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Terbium and Europium Chlorocyananilate-Based 2D Coordination Polymers"],"prefix":"10.3390","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6579-4492","authenticated-orcid":false,"given":"Mariangela","family":"Oggianu","sequence":"first","affiliation":[{"name":"Department of Chemical and Geological Sciences, University of Cagliari, Highway 554, Crossroads for Sestu, I-09042 Monserrato, Italy"},{"name":"National Interuniversity Consortium of Materials Science and Technology, INSTM, Street Giuseppe Giusti, 9, I-50121 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3883-310X","authenticated-orcid":false,"given":"Alexandre","family":"Abherv\u00e9","sequence":"additional","affiliation":[{"name":"Laboratoire MOLTECH-Anjou UMR 6200, UFR Sciences, CNRS, Universit\u00e9 d\u2019Angers, B\u00e2t.
