Abstract:

The structure of [NO_2Py]_2[Ni(mnt)_2], as determined by x-ray single crystal analysis, consists of two 1-(4-nitrobenzyl)pyridinium cations and one [Ni(mnt)_2]^2− anion. The crystallographic data for the complex:monoclinic P2_1/n, a = 9.913(2) Å, b = 11.968(2) Å, c = 14.566(3) Å, beta = 100.36(3)°, V = 1699.9(6) Å^3, Z = 2. The [Ni(mnt)_2]^2− anion has a crystallographically imposed center of symmetry and exhibits a relatively planar structure. The cation, [NO_2Py]^+, adopts a conformation where both the aromatic rings are twisted to the C11-C10-N3 reference plane. The anions (A) and the cations (C) consist of alternating layers (i.e., of type ···C_1A_1C_2A_2C_1A_1C_2···) along the c axis of the crystallographic unit cell.
