Two Mn(II)(2)Ln(III)(4) (Ln = Gd, Eu) hexanuclear compounds of p-tert-butylsulfinylcalix[4]arene.

Two 3d-4f heterometallic compounds of p-tert-butylsulfinylcalix[4]arene were synthesized by the solvothermal method and characterized by some hinged double-dumbbell-like subunits in which two perpendicular dumbbell entities were constructed by an in-between isosceles triangle Mn(II)Ln(III)(2), and two tail-to-tail calixarene molecules, and hinged by the lanthanide-sulfinyl group bonding. The magnetic properties of the title compounds were examined.
