In the title compound, [methylenebis(diphenylphosphine-P)]bis(nitrato-O)palladium(II) tris(deuteriochloroform) solvate, [Pd(NO3)(2)(C25H22P2)]. 3CDCl(3) or [Pd(NO3)(2)(dppm)]. 3CDCl(3) [where dppm is bis(diphenylphosphino)methane], the PdO2P2 unit is planar, but the molecule is significantly distorted from ideal square-planar geometry. Principal dimensions include: Pd-P 2.2240(8) and 2.2345(7), Pd-O 2.103(2) and 2.130(2) Angstrom, P-Pd-P 72.52(3), O-Pd-O 85.23(9), and P-Pd-O 97.55(7) and 104.73(6)degrees. The CDCl3 molecules associate with the complex via C-D ... O hydrogen bonds.
