The reaction of the 3,6-bis (2′-pyridyl) pyridazine (dppn) ligand, with one and two equivalents of [Rh (CO) 2Sn] (PF6) , (s = THF) , yields respectively the mononuclear complex [Rh (CO) 2(dppn) ] (PF6) 1 and the binuclear complex [Rh2(CO) 4(dppn) ] (PF6) 23. Furthermore, the reaction of 1 with PPh3results in a substitution reaction to give [Rh (CO) (dppn) (PPh3) 2] (PF6) 2. The unsaturated complex 3 reacts with the monodentate phosphine PPh3to yield a mixture of the known compound [Rh (CO) 2(PPh3) 2] (PF6) and of the mononuclear [Rh (CO) (dppn) (PPh3) ] (PF6) 4, the crystal structure of which was established by X-ray diffraction. Moreover, 3 reacts with the bis (diphenylphosphino) methane (dppm) ligand in a 1 : 2 ratio to form the binuclear A-frame complex [Rh2(CO) 2(dppn) (μ-dppm) 2] (PF6) 25. However, the reaction of 3 with excess dppm (1 : 4 ratio) gives the known complex [Rh (CO) (dppm) 2] (PF6) 6. |
