Di-μ-chlorido-bis-{[μ-1,8-bis-(diisopropyl-phosphan-yl)-9,10-dihydro-9,10-ethano-anthracene-κP:P']-μ-chlorido-μ-methyl-idene-dipalladium(II)} tetra-hydro-furan penta-solvate.

ABSTRACT: The title compound, [Pd(4)(CH(2))(2)Cl(4)(C(28)H(40)P(2))(2)]·5C(4)H(8)O, possesses a tetra-nuclear palladium core with four bridging chlorido ligands and two bridging methyl-ene units, as well as two bridging anthracene-based bis-phosphine ligands. This tetra-nuclear complex can be considered as being composed of two μ-chlorido-bridged LPd(2) units. The structural motif of these LPd(2) units shows two doubly bridged palladium centers between the P atoms of the bis-phosphine ligand. One of these bridges is a μ-Cl atom, the other a μ-methyl-ene group. The coordination environment around each palladium center is essentially square planar. We ascribe the oxidation state +II to the palladium centers and do not assume Pd-Pd bonds [shortest distances 2.8110 (5) and 2.8109 (6) Å]. Co-crystallized
