Catena-Poly[bis(4-methylbenzylammonium) [[dibromidocadmate(II)]-di-μ-bromido

Abstract

The asymmetric unit of the centrosymmetric organic–inorganic hybrid salt, {(C8H12N)2[CdBr4]} n , comprises of one 4-methylbenzylammonium cation and one half of a disordered [CdBr4]2− anion that is completed by application of mirror symmetry. The resulting CdBr6 octahedra share edges to form 2 ∞[CdBr4/2Br2/2]2− layers parallel to the ac plane. Cations and anions are connected by N—H...Br and C—H...Br hydrogen bonds. No π–π stacking interactions are observed between the benzene rings, but C—H...π interactions towards them are found.
