The reactions of the former with PhICl2 or the latter with [pyH][Br-3] provide rare examples of mu(2)-halocarbyne ligands in the complexes [Rh-2(mu-CX)(mu-X)X-4(mu-dppm)(2)] (X = Cl, Br).We gratefully acknowledge the Australian Research Council (DP170102695 and DP190100723) for funding.4enTransition-metal-complexesBridged complexesCrystal-structureCarbon-monoxideLigandsMoTetraphenylporphyrinateCations2019-02-1110.1039/c8cc09692a
