Abstract: A new five-coordinated complex [NiLCl]ClO4, where L = 1.5-bis(N-1-methylimidazol-2-methyl)-1,5-diazacyclooctane, has been synthesized and characterized by elemental analysis, IR and UV-vis spectra. The structure of the complex has been determined by single crystal X-ray diffraction (CCDC 116095). The Ni (II) atom is coordinated by four nitrogen donors of the new mesocyclic ligand L [Ni-N, 2.025(4)~2.130(4) Å], and a chloro anion from the apical site [Ni-Cl, 2.340(2) Å . The coordination geometry of the complex could be considered as a distorted square-pyramidal. The diazacyclooctane backbone has a boat/chair configuration and the two imidazole pendants are not co-planar.
