Siilver tetrafluoroborate complex of,27,28-tetrakis (diphenylphosphinoylmethoxy)calyx[4]arene (L) has been synthesized by reaction of silver tetrafluoroborate and L in dichloromethane at room temperature. The complex formed has a 1:1 metall/ligand ratio. 1H and 31P NMR data support an encapsulated structure of the complex in which silver ion is located inside the hydrophilic cavity of the ligand.
