Abstract

Syntheses and Structures of [ReNBr2(Me2PhP)3] and (Me2PhPH)[fac-Re(NBBr3)Br3(Me2PhP)2]

[ReNBr2(Me2PhP)3] (1) has been prepared by the reaction of [ReNCl2(Me2PhP)3] with Me3SiBr in dichloromethane. The bromo complex reacts with BBr3 under formation of [Re(NBBr3)Br2(Me2PhP)3] (2) or (Me2PhPH)[fac-Re(NBBr3)Br3(Me2PhP)2] (3) depending on the experimental conditions. The formation of the nitrido bridge leads to a significant decrease of the structural trans influence of the nitrido ligand which is evident by the shortening of the Re-(trans)Br bond from 2.795(1) Å in [ReNBr2(Me2PhP)3] to 2.620(1) Å in [fac-Re(NBBr3)Br3(Me2PhP)2]– and 2.598(1) Å in [Re(NBBr3)Br2(Me2PhP)3], respectively.
