An Infinite Zigzag Chain of Alternating Cl−Pd−Pd−Cl and Mo−Mo Units

Treatment of Pd2Cl2(CNC6H3Me2-2,6)4 (1) with Mo2(O2CCF3)4 (2) in dichloromethane afforded an infinite zigzag chain {[Pd2Cl2(CNC6H3Me2-2,6)4][Mo2(O2CCF3)4]} n (3), where two metal−metal bonded dinuclear Pd−Pd and Mo−Mo units were bridged by chloro atoms. The Mo−Mo distance (2.1312(3) Å) of 3 is significantly elongated compared to that of 2 (2.090(4) Å) and lies in the range of that of the quadruple Mo−Mo bonded complexes. Such elongation might be attributed to the axial donation of the chloro atoms of the Pd−Pd unit to the Mo−Mo moiety.
