摘要

Two silver( I ) complexes, {[Ag _(7) (2-pypo) _(3) (NO _(3) )]} _( n ) ( 1 ) and [Ag(3-pypoH)(3-pypoH _(2) )] ( 2 ) (pypoH _(2) – pyridylphosphonic acid) were prepared and characterized by relevant methods in the solid state (elemental, spectral, thermal and structural analysis). Typical argentophilic interactions were observed in complex 1 . The synthesized Ag( I ) complexes were tested toward reduction to silver(0) using short wavelength UV-radiation and they revealed remarkable light-insensitivity in comparison to silver nitrate. SEM experiments were performed to observe the reduction of silver after the UV-light exposure of the samples. Light-insensitivity with the examined thermal stability and insolubility of the new complexes demonstrates their high potential to be used as light-insensitive materials in medical devices.
