Bis(?(2)-phenyl-tellurolato)bis-(phenyl-tellurolato)tetra-?(3)-tellurido-hexa-kis(triphenyl-phosphine)hexa-palladium(II) benzene nona-solvate.

ABSTRACT: The centrosymmetric title complex, [Pd(6)(C(6)H(5)Te)(4)Te(4)(C(18)H(15)P)(6)]·9C(6)H(6), contains two Pd(3)Te(2) cores that are joined into a cyclic hexa-nuclear complex by two bridging PhTe(-) groups. Each Pd(II) atom is coordinated by one triphenyl-phosphine ligand, one phenyl-tellurolate mol-ecule and two telluride ligands: two of the PhTe(-) ligands act as terminal ligands and two as bridging ligands. The three distinct Pd(II) atoms each show a slightly distorted PdPTe(3) square-planar coordination. The asymmetric unit also contains four and a half benzene solvent mol-ecules. Two of the benzene mol-ecules are disordered: one mol-ecule 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.
