Abstract: The structure of the title compound, (C6H14N)2[CuCl4], consists of two inequivalent 1-methylpiperidinium cations and a flattened tetrahedral [CuCl4]2- anion. Each organic cation exhibits a chair conformation with the methyl group in the equatorial position. They are segregated into alternating layers parallel to (100) and stacked along . The first cation is arranged in parallel stacks in a herringbone pattern with rows of [CuCl4]2- anions fitting between the stacks and with a Cl- ion directed into the interior of the layer. The second organic cation forms distorted hcp layers that separate the other organic cation/[CuCl4]2- slabs. N-HCl hydrogen bonding between the cations and the anions consolidates the crystal packing.
