Structures and luminescence properties of two copper（I） halide complexes featuring 2-（2-benzimidazolyl）-6-methylpyridine

Two new copper（I） halide complexes bearing 2-（2-benzimidazolyl）-6-methylpyridine （Hbmp） and PPh3 ligands, Cu（Hbmp）（PPh3）X （X = Br （1）; I （2））, have been synthesized and characterized. Single-crystal X-ray structure analysis reveals that the halide ligand has a significant impact on the Cu-Npyridyl b...

Summary:Two new copper（I） halide complexes bearing 2-（2-benzimidazolyl）-6-methylpyridine （Hbmp） and PPh3 ligands, Cu（Hbmp）（PPh3）X （X = Br （1）; I （2））, have been synthesized and characterized. Single-crystal X-ray structure analysis reveals that the halide ligand has a significant impact on the Cu-Npyridyl bond lengths. Complexes 1 and 2 show the solid-state emissions at ambient temperature, varying with the halide bound to the { Cu（Hbmp）（PPh3） } motif, which are perhaps best attributed to the metal-to-ligand charge-transfer （Cu（I） → Hbmp） transition mixed with some ligand-to-ligand charge-transfer （X and PPh3 → Hbmp） character.
