The early-late transition metal complex Cp2Zr(CH2PPh2)2RhH(PPh3) has been prepared by the reaction of the zirconium diphosphine Cp2Zr(CH2PPh2)2 with the hydride RhH(PPh3)4.Its behaviour as a catalyst for the hydroformylation of 1-hexene under mild conditions is compared with that of related species.

Zirconium-rhodium complexes are studied with the aim of generating a zirconium-hydrogen bond by rhodium-mediated activation of dihydrogen in order to obtain highly selective catalytic synthesis. By reaction of the bis(phosphinomethyl) complex Cp2Zr(CH2PPh2)2 on Rh(H)(PPh3)4 we get the bimetallic hydride Cp2Zr(CH2PPh2)2Rh(H)(PPh 3) (3), which was structurally characterized (crystal system monoclinic, space group PZ1/n, a = 12.189 (2) ?, b = 21.054 (3) ?, c = 17.587 (2) ?, β = 98.67 (1)°, Z = 4). The most remarkable structural features of 3 are the trans chelating arrangement of the bis[(diphenylphosphino)methyl]zirconium on rhodium together with pentacoordination around zirconium due to a strong interaction of Zr on the Rh-H bond with a Zr?H distance of 2.28 (5) ?. The bimetallic system is an efficient precursor for selective catalytic hydroformylation of 1-hexene.
