Abstract

Abstract Under solvothermal reaction conditions, the reaction of 5, 6-dichloropyrazine-2, 3- dicarbonitrile and [Ni (ClO 4) 2]· 6H 2 O produces a novel cis-nickel (II) complex [NiL 2 (H 2 O) 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 (ClO 4) 2]· 6H 2 O was used instead of [Ni (ClO 4) 2]· 6H 2 O.(© Wiley-VCH Verlag ...
