(PhSe)₂Hg reacts initially with HgX₂ (X = Cl, I) and further with triphenylphosphine/DMF to give [(PhSe)₇Hg₄ClPy]_n (1) and [(PhSe)₇Hg₄I(DMF)]_n (2), polymeric assemblies of (μ-Se)Hg clusters obtained through coordinating intermediary ligands. Each single adamantoid molecule of 1 and 2 presents the Hg^II ions with a distorted tetrahedral configuration linked through asymmetric [μ-(Ph)Se]⁻ bridges. [(PhSe)₇Hg₄ClPy]_n and [(PhSe)₇Hg₄I(DMF)]_n are further examples of extended one-dimensional chains of closed anisotropic ME (E = S, Se, Te) systems. In these reactions the features of the intermediary ligands should determine the template which leads to single adamantane moieties or to fused ones.
