- Abstract
Both unique Cd atoms in the tetragonal polymorph of bis(1-ethyl-3-methylimidazolium)tetrabromidocadmate, (C6H11N2)2[CdBr4], occupy special positions(site symmetry 4). The crystal structure consists of isolated tetrahedral[CdBr4]2 anions which are surrounded by 1-ethyl-3-methylimidazolium cations.The methyl and ethyl side chains of the cations show positional disorder in a0.590 (11):0.410 (11) ratio. In the crystal, (C6H11N2)+ cations display three weakC-H...Br hydrogen-bond interactions through the imidazolium ring H atomswith the Br ligands of the surrounding complex anions. The alkyl groups of theside chains are not involved in hydrogen bonding.
