Poly[(R)-2-methylpiperazinediium [₃-chlorido-₂-chlorido-dichloridodicopper(I)]]

H.-Z. Luo and H.-Y. Ye

Abstract: The title compound, {(C₅H₁₄N₂)[Cu₂Cl₄]}_n, was synthesized by the hydrothermal reaction of CuCl₂ with homochiral (R)-2-methylpiperazine. One Cu atom has a slightly distorted tetrahedral geometry defined by one terminal and three bridging Cl^- anions, while the other displays a trigonal planar geometry composed of one terminal and two bridging Cl^- anions. The crystal structure contains a polymeric anion forming a chain running along the a axis and (R)-2-methylpiperazinediium cations filling the space between these chains. Cations and anions are connected by hydrogen bonds.
