Heterometallic quadruple bonds are very rare and although known since 1974, have been restricted to the Cr $\displaystyle\mathop{-}^{4}_{}$ Mo and the Mo $\displaystyle\mathop{-}^{4}_{}$ W cores. Now the synthesis and structure of a quadruply bonded Mo‐Re heterodimer, [(tetraphenylporphyrin)Mo $\displaystyle\mathop{-}^{4}_{}$ Re(octaethylporphyrin)]PF 6 , is reported (see picture). This complex proves that quadruple bonds can exist between elements from different triads.
