The reaction of Cd(SePh)₂ with CdX₂ (X = Cl (1), Br (2)) in MeOH in the presence of PPh₃ at 130 °C under solvothermal conditions affords the products [Cd₄(SePh)₇(PPh₃)X]_n, a one-dimensional assembly of adamantanoid [Cd₄(SePh)₆(PPh₃)X] clusters joined into a polymeric chain by μ-SePh bridges. Compounds 1 and 2 represent examples of extended one-dimensional chains of closed ME (M = metal, E = S, Se, Te) systems, whose importance is based not only on their properties, but by their possible use as precursor materials for design and development of new methodologies via a “bottom up” strategy to obtain different clusters from single components.
