A novel tetranuclear cubic cage, [Tl4(μ3-dcp)4] {Hdcp=2,4-dichlorophenol}, new short Cl⋯Cl interactions, thermal, fluorescence, structural and solution studies

The single crystal X-ray analysis of a novel TlI of 2,4-dichlorophenol (Hdcp) ligand shows that the complex is a tetranuclear cubic cage as a result of bridging ligands dcp− with basic repeating [Tl(μ3-dcp)] units. There are four thallium atoms with similar coordination spheres in the cubic cage. These thallium atoms contain irregular coordination sphere with stereo-chemically active lone.
