Counterion-induced crystallization of intermetalloid Matryoshka clusters [Sb@Pd12@Sb20]3−,4−†
Abstract
Two intermetalloid Matryoshka cluster anions [Sb@Pd12@Sb20]3−,4− obtained from the reaction of KSb and Pd(PPh3)4 were isolated as [K(2,2,2-cryptand)]+ and [K(18-crown-6)]+ salt, respectively, and characterized by X-ray crystallography, EPR measurement and DFT theoretical calculations.
