A red luminescent organic-inorganic hybrid network with double-stranded zigzag [Cu4I4]_n chains

摘要

A novel red luminescent coordination polymer, [Cu2I2(bmt)]_n·nDMF (1), was synthesized from the solution reaction of CuI and heterocyclic thione ligand, benz-1,3-imidazole-2-thione (bmt). Single-crystal analysis shows that its unusual organic-inorganic hybrid framework built-up from the distorted double-stranded zigzag [Cu4I4]_n chains with organic bmt ligands. Emission properties of 1 in solid state at room temperature and 10 K were investigated.
