Deskripsi
The centrosymmetric title complex, [Pd6(C6H5Te)4Te4(C18H15P)6]·9C6H6, contains two Pd3Te2 cores that are joined into a cyclic hexanuclear complex by two bridging PhTe− groups. Each PdII atom is coordinated by one triphenylphosphine ligand, one phenyltellurolate molecule and two telluride ligands: two of the PhTe− ligands act as terminal ligands and two as bridging ligands. The three distinct PdII atoms each show a slightly distorted PdPTe3 square-planar coordination. The asymmetric unit also contains four and a half benzene solvent molecules. Two of the benzene molecules are disordered: one molecule is distributed over two positions with site-occupancy factors of 0.529 (7) and 0.471 (7), while the other occupies two orientations about a centre of symmetry.
