Bis[2,6-bis-(benzimidazol-2-yl)pyridine-κ(3)N,N',N'']nickel(II) bis-(tri-fluoro-methane-sulfonate) diethyl ether monosolvate.

In the title complex, [Ni(C(19)H(13)N(5))(2)](CF(3)SO(3))(2)·(CH(3)CH(2))(2)O, the central Ni(II) atom is sixfold coordinated by three nitro-gen atoms of each 2,6-bis-(2-benzimidazol-yl)pyridine ligand in a distorted octa-hedral geometry with two tri-fluoro-methane-sulfonate ions and a mol-ecule of diethyl ether completing the outer coordination sphere of the complex. Hydrogen bonding contributes to the organization of the asymmetric units in columns along the a axis generating a porous supra-molecular structure. The structure was refined as a two-component twin with a refined BASF value of 0.4104†(13).
