Heterometallic Binuclear Complexes, I. — Reactive Zr(IV)‐M(0) Compounds (M = Cr, Mo, W) with Bridging Diphenylphosphinocyclopentadienide Ligands Reaction of ZrCl 2 (C 5 H 4 PPh 2 ) 2 ( 1 ) with labile complexes M(CO) 3 L 3 (M = Cr, L = acetonitrile, M = Mo, W, L 3 = cycloheptatriene) gives the binuclear compounds ZrCl(μ‐Cl)(μ‐C 5 H 4 PPh 2 ) 2 M(CO) 3 [M = Cr ( 2 ), Mo ( 3 ), W ( 4 )]. The Cl bridge is readily cleaved by ligands such as CO, MeCN, or P(OMe) 3 .
