Under solvothermal reaction conditions, the reaction of 5,6-dichloropyrazine-2,3-dicarbonitrile and [Ni(ClO4)2]·6H2O produces a novel cis-nickel(II) complex [NiL2(H2O)4] (1) (L = 1,4-dihydropyrazine-2,3-dione-5,6-dicarboxylate), whereas only hydrated 1,4-dihydropyrazine-2,3-dione-5,6-dicarboxylic acid (2) was obtained as a single phase when [Cd(ClO4)2]·6H2O was used instead of [Ni(ClO4)2]·6H2O.
