In this paper, two ion-pair compounds containing bis (maleated dicyanodithiolene) nickel complex anions were reported. When cations are 1- (4’-bromo-2’-fluorobenzyl) pyridinium salt, complex 1 is formed. Crystal data: triclinic system with space group P1 珔, a = 0.7086 (2) nm, b = 1.0968 (3) nm, c = 1.1775 (3) nm, α = 69.914 ) °, γ = 74.765 (5) °, V = 0.8259 (4) nm3, Z = 1. When the cation is 1- (4’-bromo-2’-fluorobenzyl) pyrazine, the complex 2 is formed. Crystal data: monoclinic, space group P21 / n, a = 0.71554 (17) nm, b = 1.4262 (3) nm, c = 1.6725 (4) nm, β = 100.396 (4) °, V = 1.6788 7) nm3, Z = 4. In the two complexes, the anions are pseudo-planar structures and the nickel atoms are located at the center of symmetry. The type of aromatic ring on the cation affects the packing structure of the crystal.
