• tetranuclear cage

The single crystal X-ray analysis of a novel Tl-1 complex of 2,4-dichlorophenol (Hdcp) ligand shows that the complex has a tetranuclear cubic cage as a result of bridging ligands dcp(-) with basic repeating of [Tl(mu(3)-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 tone pair. The thermal stability of [Tl-4(mu(3)-dcp)(4)] was studied by thermal gravimetric (TG) and differential thermal analyses (DTA). The compound [Tl-4(mu(3)-dcp)(4)] is luminescent in the solution state with emission maxima at 397 nm. The results of studies of the stoichiometry and formation of [Tl-4(mu(3)-dcp)(4)] Complex in DMF solution were found to be in support of their solid state stoichiometry.
