SYNTHESIS, CHARACTERIZATION AND CRYSTAL STRUCTURE OF A POLYMERIC SILVER(I) COMPLEX WITH CYTOTOXIC PROPERTY
A new polymeric silver(I) complex, [Ag2(L¹)2(L²)(OH2)]n, was obtained by the reaction of 3-aminopyrazine-2-carboxylic acid (HL¹), 2-amino-5-methylpyridine (L²) and silver oxide in aqueous ammonia. The complex was characterized by elemental analysis, IR spectra and single crystal X-ray determination....
