Abstract

We report the first crystallographically characterized dimethylaniline complex of a group 4 metallocene. [(IPCF)ZrMe(NMe₂Ph)][B(C₆F₅)₄] shows strongly coordinated NMe₂Ph which does not interchange in solution. DFT calculations suggest that the Zr-N bond is 23 kJ mol^-1 stronger than the Zr-Me-Zr bond in [{(IPCF)ZrMe}₂(µ-Me)][MeB(C₆F₅)₃], the structure of which is also reported (IPCF = Me₂C(C₅H₄)(fluorenyl)).
