Synthesis and crystal structure of a luminescent infinite 2D brick-wall network with two- and three-coordinate silver(I) atoms and ligand-unsupported silver–silver interactions

Abstract

Assembly of a novel flexible tetradentate ligand 1,7-bis(4′-pyridyl)-2,6-diazaheptane (py-hep) with silver perchlorate hydrate provides an interesting two-dimensional (2D) brick-wall network: [Ag3(py-hep)2](ClO4)3·0.5CH3CN. The X-ray crystal structural analysis indicates that the framework consists of trigonal and linearly coordinated silver(I) atoms and ligand-unsupported metal–metal interactions. The complex shows photoluminescence in both the solid state and in acetonitrile solution.
