Synthesis, crystal structure and Hirshfeld surface analysis of bromidotetrakis[5-(prop-2-en-1-ylsulfanyl)-1,3,4-thiadiazol-2-amine-κ<i>N</i> <sup>3</sup>]copper(II) bromide
Аннотация
A novel cationic complex, bromidotetrakis[5-(prop-2-en-1-ylsulfanyl)-1,3,4-thiadiazol-2-amine-κ N 3 ]copper(II) bromide, [CuBr](C 5 H 7 N 3 S 2 ) 4 Br, was synthesized. The complex crystallizes with fourfold molecular symmetry in the tetragonal space group P 4/ n . The Cu II atom exhibits a square-pyramidal coordination geometry. The Cu atom is located centrally within the complex, being coordinated by four nitrogen atoms from four AAT molecules, while a bromine anion is located at the apex of the pyramid. The amino H atoms of AAT interact with bromine from the inner and outer spheres, forming a two-dimensional network in the [100] and [010] directions. Hirshfeld surface analysis reveals that 33.7% of the intermolecular interactions are from H...H contacts, 21.2% are from S...H/H...S contacts, 13.4% are from S...S contacts and 11.0% are from C...H/H...C, while other contributions are from Br...H/H...Br and N...H/H...N contacts.
