Compared to previously reported methods, a less hazardous approach has been used to synthesize N-methylpyrazinium cation (mpz+) by the reaction of pyrazine and ClCH2COONa. Although a few mpz+-containing complexes have been documented, there is no example of mpz+-containing group IIB metal complexes. Three novel complexes containing mpz+,(mpz) ZnI3 (1),[(mpz) CdCl3] n (2), and [(mpz) CdBr3] n (3), have been ...
