Abstract: The title compound, [Pd₂(C₈H₄N₆)₂(C₃H₉P)₄], was prepared by treating Pd(PMe₃)₂(N₃)₂ with 1,4-phenylene diisocyanide [C₆H₄(NC)₂]. This compound, a cyclic dimer, was formed by concomitant N-C coupling and [2 + 3]-cycloaddition. Around the square-planar Pd atom, the carbodiimide moiety and the tetrazolate ring are mutually trans. The N atom of the carbodiimide moiety is bonded to the Pd center, and the five-membered tetrazolate ring is coordinated to the Pd atoms through the C atom. The molecule is located on a center of symmetry.
