Rh(I) cyclooctadiene (cod) and carbonyl complexes with fluorinated 2,2′-bipyridines (N-N) have been prepared. The fluorinated tail was introduced as an alky group or through an ester function in the 4,4′- or 5,5′-positions. The X-ray structure of the cyclooctadiene complexes [Rh(cod)(4)][PF6] and [Rh(cod)(L4)][PF6] shows the square-planar coordination around the metal centre, and, in the case of complex with the ester function [Rh(cod)(4)][PF6] the fluorinated tails adopt a relative anti disposition of the ester groups. The electronic properties of the N-N ligands were studied through the stretching ν(CO) infrared frequencies of the corresponding carbonyl complexes [Rh(CO)2(N-N)][PF6].

► New Rh(I) complexes with fluorinated bipyridines have been prepared.
► The electronic properties of the fluorinated bipyridines are similar to those non-fluorinated.
► The X-ray structure of the Rh(I) cyclooctadiene complexes with fluorinated bipyridines have been determined.
