The \u03bc1,5 bridging models of the dicyanamide ligand linked the macrocycle to form in a specific size with the chair conformation. The anion was important to form this 36-metallacrown-6 complex, as change was obtained with the larger anion BPh4\u2212, binuclear copper compound 2. The magnetic property indicates that slightly ferromagnetic interactions resulted from a superexchange mechanism. DNA binding properties were also studied. UV and fluorescence spectra showed that complex 1 could bind with DNA.<\/jats:p>","DOI":"10.3390\/molecules23061269","type":"journal-article","created":{"date-parts":[[2018,5,28]],"date-time":"2018-05-28T03:54:21Z","timestamp":1527479661000},"page":"1269","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Dicyanamide Bridged Cu(II)36-Metallacrown-6 Complex with 1,4,7-Triisopropyl-1,4,7-Triazacyclononane and Binding Properties with DNA"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6997-4530","authenticated-orcid":false,"given":"Yong-Sheng","family":"Yang","sequence":"first","affiliation":[{"name":"Hubei Key Laboratory of Biomass Fibers and Eco-dyeing &amp; Finishing, School of Chemistry and Engineering, Wuhan Textile University, 1 Textile Road, Wuhan 430073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li-Jun","family":"Liu","sequence":"additional","affiliation":[{"name":"Hubei Key Laboratory of Biomass Fibers and Eco-dyeing &amp; Finishing, School of Chemistry and Engineering, Wuhan Textile University, 1 Textile Road, Wuhan 430073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hai-Yan","family":"Ju","sequence":"additional","affiliation":[{"name":"Hubei Key Laboratory of Biomass Fibers and Eco-dyeing &amp; Finishing, School of Chemistry and Engineering, Wuhan Textile University, 1 Textile Road, Wuhan 430073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiu-Ying","family":"Liu","sequence":"additional","affiliation":[{"name":"Hubei Key Laboratory of Biomass Fibers and Eco-dyeing &amp; Finishing, School of Chemistry and Engineering, Wuhan Textile University, 1 Textile Road, Wuhan 430073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu-Guang","family":"Li","sequence":"additional","affiliation":[{"name":"Hubei Key Laboratory of Biomass Fibers and Eco-dyeing &amp; Finishing, School of Chemistry and Engineering, Wuhan Textile University, 1 Textile Road, Wuhan 430073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shi-Ping","family":"Yan","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Nankai University, Tianjin 300071, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,5,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4148","DOI":"10.1039\/C5SC01029B","article-title":"Assessing the exchange coupling in binuclear lanthanide(III) complexes and the slow relaxation of the magnetization in the antiferromagnetically coupled Dy2 derivative","volume":"6","author":"Chow","year":"2015","journal-title":"Chem.
