Abstract

Department of Chemistry, Banaras Hindu University, Varanasi-221 005, India E-mail : lmishra@banaras.ernet.in Fax : 91-542-368174 Manuscript received 2 April 2001 Multifunctional ligand 5-cyano-6-(4-pyndyl)-2-thiouracil (L) possessing hydrogen bonding groups complementary to those found in nucleotide bases has been synthesiud and compleud with trans-[Co(en)2Cl2 ]+Cl- (en= ethylene diamme) resulting into two types of complexes [Co(en)2LCI]2+.LCI2+. 2CI- and [Co(en)2L2I]3+.3CI-. These complexes were allowed to react with thymine (T) and adenine (A) bases separately. Solid complexes thus synthesized have been characterized using elemental analysis, FAB mass, spectral (IR, UV-visible, 1H NMR) and scanning electron microscopic (SEM) studies. Association of ligand (L) and its one representative complex [Co(en)2LCI]2+.2CI- with thymine base has been studied by UV-visible spectrophotometry.
