1,2-Bis[(5-H/methyl/chloroitro)-2-1H-benzimidazolyl]-1,2-ethanediols and 1,4-bis[(5-H/methyl/chloro)2-1H-benzimidazolyl]-1,2,3,4-butanetetraols complexes with AgNO_3

摘要

The complexes of 1,2-Bis-[(5-H/methyl/chloroitro)-2-1H-benzimidazolyl]-1,2-ethanediols (L1-L4) and 1,4-Bis-[(5-H/methyl/chloro)-2-1H-benzimidazolyl]-1,2,3,4-butanetetraols (L5-L7) with AgNO_3 were synthesized and characterized using elemental analysis, molar conductivity, IR, ~1H-NMR spectroscopy. All of the complexes have ionic character. Ag(I) complexes of L1-L4 have 1:1 M:L ratio, whereas those of L5-L7 have 2:1 M:L ratio. It was determined that the ligands are coordinated to Ag(I) ion through hydroxy oxygen atoms only.
