N2 - The complexes [NO2BzPz]2[Ni(mnt)2] (1) and [BrBzPz]2[Pd(mnt)2] (2) have been prepared by reaction of Na2mnt, NiCl2·6H2O or PdCl2, and the corresponding 1-(R-benzyl)pyrazinium bromide salt (R = 4′-nitro, R = 4′-bromo). Crystallographic data for 1: monoclinic, P21/n, a = 7.3494(15), b = 15.223(3), c = 15.054(3)Å, β = 102.42(3)°, V = 1644.8(6)Å3, Z = 2. Data for 2: monoclinic, P21/n, a = 7.399(2), b = 19.024(4), c = 12.224(2) Å, β = 94.62(3)°, V = 1715.0(7) Å3, Z = 4. In both complexes, the [M(mnt)2]2- anion has a centre of symmetry at the metal atom and two cations are related to each other by the symmetry centre. The [M(mnt)2]2- anion exhibits a quasi-planar structure in both complexes, which show similar crystal packing.
