Crystal and molecular structure of bis(quinoline)bromine perchlorate

Abstract

The crystal structure of the title compound has been determined by single-crystal X-ray methods (2 739 reflections) and refined to R 0.075 by use of rigid-body methods. Crystals are monoclinic, space-group Ca[non-standard] with a= 17.061(1), b= 30.803(2), c= 6.837(1)Å, γ= 90.18(1)°, Z= 8. The principal features are the cations. Each of two independent ions has a Br⁺ ion co-ordinated linearly by two quinoline molecules with Br–N 2.10– 2.18 Å. The coplanar quinoline molecules are related by approximate centres of symmetry at Br.
