The title compound, [Pd(C5H9N)(C8H11P){B9H8As2- (C8H11P)}][SbF6], cont
ains a twelve-vertex (PdAs2B9) cage with the metal eta(5)-bonded to an
AS(2)B(3) ring. The exo-cage ligands dimethylphenylphosphine and tert
butyl isocyanide are attached to Pd and a second PMe(2)Ph ligand is at
tached to a cage B atom at position 8. The Pd-As interactions are nota
bly asymmetric at 2.6434(8) and 2.5296(7)Angstrom. Other principal dim
ensions are Pd-B 2.291(6)-2.301, Pd-P 2.330(2), Pd-C 2.011(6) and As-A
