Reaction of Mo2(pyphos)4 (1) (pyphos = 6-diphenylphosphino-2-pyridonate) with Pd(dba)2 (dba = dibenzylideneacetone) afforded the Pd(0) complex Mo2Pd2(pyphos)4 (2) which has two Pd(0) centers at both axial positions of the Mo2 core. The unsaturated Pd(0) centers of 2 were coordinated with donor molecules such as olefins, acetylenes, isonitriles, carbon monoxide, and triphenylphosphine to give the corresponding
