Direct synthesis and structural characterisation of tri- and tetra-nuclear silver metallaknotanes by self-assembly approach

Abstract

The combination of ligands based on two quinoline units acting as primary coordinating sites connected by tetra- or penta-ethyleneoxy fragments behaving as secondary interaction sites leads spontaneously in a one-pot reaction to the formation of tri- and terta-nuclear metalla-organic knots in the presence of silver cation.
