Step-by-step solution

( [F e F₆ ]³⁻ ) complex ion possesses sp (³ d² ) hybridization. The electronic configurations of (C r, F e, C o ) and (T i ) in the complexes are ((3 d)³,(3 d)⁵,(3 d)⁶ ) and ((3 d)¹ ), respectively. These involve (d² s p³, s p³ d², d² s p³ ) and (d² s p³ ) hybridization respectively.
