surprisingly, the structure of [Pd(triphos)(NCCH3)] 2+ has not been reported for comparison. The P1-Pd-C1 angle of 169.5(3)° and P2-Pd-P2' angle of 163.86(6)° are both distinctly bent, creating a slight tetrahedral distortion within the otherwise square planar geometry. The unit cell of 1 has four Pd cations (Z = 4); for each cation there is an associated BF4 anion and two symmetry-equivalent molecules of CD3CN, the latter of which is disordered over two overlapping positions. The positions of the cocrystallized solvent molecules could be identified clearly from the electron density map, and they refined to chemically sensible geometries, albeit with extensive use of restraints. However, refinement of their thermal displacement parameters did not converge well even with the aforementioned restraints. Therefore, for the final refinement, the SQUEEZE function of the PLATON program was used to remove the contribution of these solvent molecules from the structure.
