title: Tetra-pyridine-bis(trichloro-acetato)nickel(II).
abstract: The title compound, [Ni(C(2)Cl(3)O(2))(2)(C(5)H(5)N)(4)], was prepared by the reaction of pyridine and trichloro-acetatonickel(II) in ethanol solution at room temperature. The Ni(II) atom is located on a twofold rotation axis and has a slightly distorted octa-hedral coordination made up of four N atoms of the pyridine ligands and two O atoms of trichloro-acetate anions. The mol-ecular structure and packing are stabilized by intra- and inter-molecular C-H⋯O hydrogen-bonding inter-actions.
