The crystal structure of title compound, N-Benzyl-N′,N′-dimethyl-N-(2-pyridinio)-1,2-ethanediammonium tetratetrachlorocobaltate(II), (C16H23N3)[CoCl4], contains the dihydro cation of tripelennamine, an anti-allergic drug effective on H1-type receptors. The molecular dimensions in the cation are normal. Two Cl atoms of the anion are involved in hydrogen bonds with different cations, with NCl distances of 3.099 (5) and 3.225 (5) Å. The CoCl42− anion exhibits a slightly distorted tetrahedral geometry.
