摘要:
The crystal structure of N-(4-chlorobenzyl)-N',N'-dimethyl-N-(2-pyridinio)-1, 2-ethanediammonium tetrachlorocopper(II), (C16H22ClN3)[CuCl4], contains the dication of chloropyramine, a potent anti-allergic agent effective on H-1-type receptors. The CuCl42- anion exhibits a flattened-tetrahedral geometry. The ammonium H atom is weakly bonded to two Cl atoms of the anion and the pyridyl N atom is involved in a short hydrogen bond to a Cl atom of the anion.
