Аннотация:The formation of coordination polymeric chain structures in which silver ions alternate
with dipyridylethylene (DPyEt) ligands was studied. In a homogeneous ethanol solution,
complex formation of DPyEt with silver cations takes place. The outcome of this reaction
depends on the ligand/cation molar ratio, the initial ligand concentration, and the counterion
type. Conditions were identified under which the coordination polymer is formed as
a microdispersed solid precipitating from the solution. The precipitates formed in the
DPyEt—AgNO3 and DPyEt—AgClO4 systems were investigated by various experimental tech
niques. The counterion was found to be incorporated in the polymer and to influence the
structure of the precipitate particles.
