Popis:	The synthesis and crystal structure of a novel ion-pair complex, 1-(2′,4′-dichlorobenzyl)-2-methylpyrazinium-bis(maleonitriledithiolate)nickelate(II), are reported. The compound is triclinic, space group P with a = 9.079(2), b = 10.154(2), c = 11.243(2) A, α = 81.58(1), β = 69.63(1), γ = 68.02(1)°, Z = 1. The [Ni(mnt)2]2− anion exhibits a relatively planar structure and the cation, [DiClBzMePz]+, adopts a conformation where both the phenyl ring and the pyrazine ring are twisted with respect to the C(10)–C(9)–N(3) reference plane. In the solid state, the cations (D) and anions (A) form a 1D alternating column of the type –D1D2A1D1D2A2D1D2– along the c axis through π–π and Ni(1) ··· N(3) interactions between and [DiClBzMePz]+. Extensive hydrogen bonding further stabilizes a 2D structure.
