title: Crystal structure of 1-[2-(di-ethyl-aza-n-ium-yl)eth-yl]-3-methyl-imidazolium tetra-chlorido-cuprate(II).
abstract: The title compound, (C10H21N3)[CuCl4], is composed of one 1-[2-(di-ethyl-aza-nium-yl)eth-yl]-3-methyl-imidazolium dication and a tetra-chlorido-cuprate(II) dianion. The anion adopts a distorted tetra-hedral geometry. Bifurcated interionic N-H⋯Cl hydrogen bonds and several C-H⋯Cl contacts are observed, leading to a layer-like arrangement of the components parallel to (100).
