catena-Poly[N-methylmorpholinium [nickelate(II)-tri--chlorido]]

M. M. Turnbull

Abstract: The structure of the title complex, {(C₅H₁₂NO)[NiCl₃]}_n, shows pseudo-octahedral geometry about the Ni^II ions with discrete N-methylmorpholinium cations. The cation has mirror symmetry; Ni and one Cl atom also lie on a mirror plane. The Ni atoms are linked via bridging Cl ions into a linear chain parallel to the a axis. The bridging Cl ions create a pseudo-octahedral geometry about each Ni atom with a Jahn-Teller compression. Bifurcated N-HCl hydrogen bonding occurs between the cations and anions.
