Water-soluble silver(i) complexes of (β)-(+)- And (S)-(-)-2pyrrolidone-5-carboxylic acid and their antimicrobial activities. Chiral helical polymer and polymer sheet structures in the solid-state formed by self-assembly of dimeric [Ag(Hpyrrld)]2 cores

The synthesis and characterization of two water-soluble silver(i) complexes {[Ag(-R-Hpyrrld)]2} l and {[Ag2(β-Hpyrrld)(S-Hpyrrld)]} 2 [R- and S-H2pyrrld = (￡)-(+)- and (5)-(-)-2-pyrrolidone-5-carboxylic acid, respectively] showing wide ranging effective antimicrobial activity are described and their crystal structures determined. Single-crystal X-ray analysis reveals that 1 and 2 in the solid state are a right-handed chiral helical polymer and an achiral polymer sheet, respectively, formed by self-assembly of the Ag2(carboxylato-O,O')2 units [Ag-Ag 2.899(2) A for 1 and 2.875(2) A for 2; O-Ag-O 160.3(5), 163.2(5)° for 1 and 163.1(2)° for 2J. The helicity of 1 in the solid state was accomplished by connection of only one oxo group in one dimeric core to one of the silver(i) centers of the adjacent dimeric unit. It is elucidated that the chiral helical polymer lisa mirror image of the recently characterized enantiomer {[Ag(S-Hpyrrld)]2} 3. The bonding modes of 1 and 3 are quite different from those of the achiral polymer sheet 2. Complexes 1 and 2 have been also characterized by elemental analysis, TG/DTA, FT-IR, and solution ('H and I3C) and solid-state I3C NMR spectroscopies. The wide ranging effective antimicrobial activities observed in the complexes suggest that weak silver(i)-oxygen bonding properties play a key role. The Royal Society of Chemistry 2000.
