Abstract: | The crystal structure of the title complex, [Ni(C6H14N2)2]Br2, consists of discrete [Ni(C6H14N2)2]2+ cations and bromide counter‐anions. The NiII ion is at the center of symmetry and is four‐coordinated by four nitrogen donors of the mesocyclic ligand 1,5‐diazacyclooctane (DACO) [Ni—N 1.935 (2)–1.937 (2) Å]. The coordination geometry of NiII can be considered as square planar and both DACO ligands take the boat–chair conformation. The bromide anions are hydrogen bonded with the nitrogen donors of the ligands to form a macrocycle‐like ring system. |
