N2 - [BrFPy]2[Ni(dto)2] (1) and [BrPy]2[Ni(dto) 2] (2) complexes have been prepared by reaction of Na 2[Ni(S2C2O2)2] and the corresponding 1-(Rbenzyl)pyridinium bromide salt (R1 = 4′-bromo-2′-fluoro, R2 = 4′-bromo). The crystallographic data for 1: monoclinic P21/c, a = 14.2192(1) Å, b = 14.2533(4) Å, c = 15.6535(3) Å, β = 96.463(1)°, V = 3152.34(11) Å3, Z = 4. Two cations, [Br1F1Py]+ and [Br2F 2Py]+, both adopt a conformation where both the aromatic rings are twisted to the corresponding N(1)-C(10)-C(11) or N(2) - C(22) - C(23) reference plane. Data for 2: triclinic P1̄, a = 9.4042(3) Å, b = 9.6814(4) Å, c = 10.3357(4) Å, α = 80.155(1)°, β = 65.245(1)°, γ = 64.259(1)°, V = 769.68(5) Å3, Z = 1. The [Ni(dto)2]2- anion exhibits a quasi-planar structure in both complexes. An extensive hydrogen bond network of C-H ⋯ O is clearly observed in 1 and 2, and two complexes show similar crystal packing.
