Solvothermal synthesis and crystal structure of a polymeric network assembled by tetranuclear [Sm4(en)4(μ3-OH)4]8+ clusters and sulfate anions

A novel samarium hydroxyl sulfate, [Sm(en)(μ3-OH)(μ3-SO4)]∞, was synthesized by a solvothermal method and the structure of the coordination polymer takes a diamond-like network assembled by tetranuclear cubane-like [Sm4(en)4(μ3-OH)4]8+ clusters and η3-SO42- ion bridges.
