  Crystal structures and photoluminescence of the Zn(II) and Cd(II) complexes of N-methylpyrazinium obtained by a less hazardous approach

  摘要：

  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 successfully obtained via a solution or hydrothermal method by reactions of ZnI2, CdCl2 center dot 2.5H(2)O, and CdBr2 center dot 4H(2)O with the mpz(+) ligand, respectively. Complex 1 features an isolated structure, with each zinc atom coordinated by one mpz+ ligand and three terminal iodine atoms. The CD spectra of I reveal that it exhibits spontaneous resolution. Complexes 2 and 3 are isotypic, and exhibit chain structures made by linear arrays of Cd(II) bridged by halogen atoms. Photoluminescent analyses reveal that complexes 1-3 exhibit strong blue emissions originating from intra-ligand pi-pi* transition of the mpz(+) ligand. (C) 2009 Elsevier B.V. All rights reserved.
