The Pd atom in the title compound, [Pd(C(18)H(14)O(3)P)Cl(C(5)H(8)N(2))], adopts a slightly distorted square-planar coordination geometry, with the metallated carbon positioned trans to the Cl atom. The crystal structure is stabilized by several weak C-H⋯O and C-H⋯Cl hydrogen-bond inter-actions. One of the phenyl rings is disordered over two almost equally occupied sites.
