 Title    Stereoselective Synthesis o f a Phenylphosphido-Bridged Dimetallic Complex: Crystal and Molecular Structure of [(R * ,R * ),(R * )]-(± )-[(i/5-C5H 5){l,2 -C 6H 4(PM ePh)2}FePH Ph{Cr(CO )5}]- 2 H20 * 0.5 CH2C12 * 0.5 C4H 80  
 Abstract    D eprotonation of (R * ,R *)-(±)-[(^ -C 5H 5){l,2-C 6H 4(PM ePh)2}Fe(PH 2Ph)]PF6 with «-BuLi in tetrahydrofuran at 20 °C, followed by treatm ent of the interm ediate phenylphosphido-iron complex with [Cr(CO)5(NM e3)] produces a separable 3 :2 mixture of the diastereom ers [(R* ,R*),(R*)]-and [(R*,R*),(S*)]-(±)-'[(/75-C5H 5){ l,2 -C 6H 4(PM ePh)2} F e -P H (P h) -*■ C r(C O)5], The m ajor com po­ nent of the mixture crystallizes from dichlorom ethane-tetrahydrofuran in the atm osphere as the mixed solvate [(R *,R *),(R *)]-(±)-[(/75-C5H 5){ l,2 -C 6H 4(PM ePh)2} F e -P H (P h) -* C r(C O)5]-2 H 20 0.5C H iC l2-0.5 C 4H 80 in the triclinic space group P I with two formula units in the unit cell; the lattice constants are a = 10.933(2) Ä , b = 13.161(4) Ä ,c = 15.249(3) A, a = 76.83(1)°, 0 = 75.62(3)°, and y = 79.31(1)°. In the structure, the pyram idal phenylphosphido group bridges the dissimilar metals via relatively long m etal-phosphorus bonds, v iz., Fe —P = 2.285(5) Ä, C r—P = 2.511(4) Ä.
