摘要：
The syntheses of [(C5H4SiMe3)2Zr(PPh2)2] (1) and [(C5H5)(C5Me5)Zr(PPh2)2] (2) are described. The X-ray crystal structure of 1 has been determined (monoclinic, P2(1)/n; a = 17.951(8); b = 23.776(11); c = 9.163(10) angstrom; beta = 99.29(6)-degrees; Z = 4) and it contains two distinct types of phosphido-ligands. Cyclic voltammetry measurements and chemical reduction of 1 are described, and the monophosphido Zr(III) adduct species, [(C5H4SiMe3)2Zr(PPh2)(PhC=CH)] identified by electron spin resonance spectroscopy. Reaction of 1 with the rhodium complex [Rh2(mu-S-tBu)2(CO)4] affords the heterometallic complex [{C5H4SiMe3)2Zr(mu-PPh2)2(Rh(mu-S-tBu)2Rh}(mu-PPh2)2Zr(C5H4SiMe3)2](3). The catalysis of the hydroformylation of 1-hexene with 3 as catalyst has been investigated.
