{α,α'-Bis[(-but-yl)(6-meth-oxy-pyridin-2-yl)phosphino]--xylene}(η--methyl-maleinimide)palladium(0) toluene hemisolvate.

The solvated title compound, [Pd(CHNO)(CHNOP)]·0.5CH, consists of a palladium(0) atom coordinated by a chelating α,α'-bis-[(-but-yl)(6-meth-oxy-pyridin-2-yl)phosphino]-xylene ligand and an η-coordinating -methyl-maleinimide mol-ecule to generate a 16 electron complex in which the metal atom has a pseudo-square-planar coordination environment. The co-crystallized toluene solvent mol-ecule is disordered about an inversion centre by symmetry. Weak C-H⋯O and C-H⋯N hydrogen bonds connect the components in the extended structure.
