In complex 1, two cis-coordinated ligands combine with two copper ions to form an unabridged 24-membered macrocycle. Each copper ion is five-coordinated with two nitrogens from separate ligands, two nitrogens from thiocyanates and one oxygen from the dimethylformamide (DMF) solvent. Complex 1 has been characterized using single-crystal X-ray diffraction, optical and thermal analyses and antimicrobial activity measurements. The solid electron paramagnetic resonance (EPR) analysis of complex 1 yielded a characteristic structural g factor value of 2.147. In addition, the thermal analysis established that the complex is thermally stable at up to 176 \u00b0C. The antimicrobial activity measurements demonstrated that both the ligand and complex 1 exhibit an inhibitory effect on two strains, where the complex exhibits a significantly greater inhibition relative to that of the free ligand (p &lt; 0.05).<\/jats:p>","DOI":"10.3390\/sym17050791","type":"journal-article","created":{"date-parts":[[2025,5,20]],"date-time":"2025-05-20T06:54:28Z","timestamp":1747724068000},"page":"791","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Synthesis, Structural Characterization, EPR Analysis and Antimicrobial Activity of a Copper(II) Thiocyanate Complex Based on 3,7-Di(3-pyridyl)-1,5-dioxa-3,7-diazacyclooctane"],"prefix":"10.3390","volume":"17","author":[{"given":"Wei","family":"Qian","sequence":"first","affiliation":[{"name":"School of Chemistry and Life Sciences, Suzhou University of Science and Technology, Suzhou 215009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zibo","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Life Sciences, Suzhou University of Science and Technology, Suzhou 215009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingfeng","family":"Xia","sequence":"additional","affiliation":[{"name":"School of Chemistry and Life Sciences, Suzhou University of Science and Technology, Suzhou 215009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongxia","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Life Sciences, Suzhou University of Science and Technology, Suzhou 215009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuling","family":"Dong","sequence":"additional","affiliation":[{"name":"School of Chemistry and Life Sciences, Suzhou University of Science and Technology, Suzhou 215009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuai","family":"Lou","sequence":"additional","affiliation":[{"name":"School of Chemistry and Life Sciences, Suzhou University of Science and Technology, Suzhou 215009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ping","family":"Ding","sequence":"additional","affiliation":[{"name":"School of Material Science and Engineering, Suzhou University of Science and Technology, Suzhou 215009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li","family":"Li","sequence":"additional","affiliation":[{"name":"School of Chemistry and Life Sciences, Suzhou University of Science and Technology, Suzhou 215009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"110085","DOI":"10.1016\/j.jpcs.2021.110085","article-title":"Structures, bonding, and electronic properties of metal thiocyanates","volume":"154","author":"Wechwithayakhlung","year":"2021","journal-title":"J.
