The the title compound, isolated after a Sonogashira coupling reaction, crystallizes in the monoclinic space group C2/c.
The title palladium complex, [Pd(C6H3N2)2(C18H15P)2], was isolated as an impurity that co-eluted with the organic product of a palladium-catalyzed Sonogashira coupling. It crystallizes in the monoclinic space group C2/c with one half of the complex in the asymmetric unit. The palladium atom (site symmetry
) has a square-planar geometry with trans phosphine ligands. The P—Pd—C angle is 95.19 (9)°.
