Tetrakis(acetonitrile)‐dibromo‐nickel(II)‐di‐acetonitrile, [Ni(CH 3 CN) 4 Br 2 ]·2CH 3 CN

[Tetrakis(acetonitrile)‐dibromo‐nickel(II)]‐di‐acetonitrile was obtained from a solution of nickel(II) dibromide in acetonitrile at 258 K. The crystal structure [monoclinic, P 2 1 / n (no.14), a = 1005.5(5), b = 831.3(5) , c = 1131.7(5) pm, β = 106.263(5)°, V = 908.1(8)·10 6 pm 3 , Z = 2, R 1 for 1580 reflections with I 0 >2σ(I 0 ): 0.0505] contains sixfold coordinated Ni II atoms. Two trans coordinating bromide anions and four equatorial acetonitrile molecules form an elongated octahedron around the central Ni II atom. [Ni(CH 3 CN) 4 Br 2 ] octahedra are connected via hydrogen bonds to neighboring octahedra as well as to solvate acetonitrile molecules.
