The synthesis and characterization of two N‐heterocyclic carbene (NHC) complexes of titanium (IPr)Ti(NMe 2 ) 2 Cl 2 ( 1 ) [IPr = 1,3‐bis(2,6‐diisopropylphenyl)imidazol‐2‐ylidene] and (IPr) 2 TiCl 3 ( 2 ) are described. Reactions of one and two equivalents of IPr with Ti(NMe 2 ) 2 Cl 2 and TiCl 3 (thf) 3 yield the mono‐NHC titanium(IV) complex 1 and the bis‐NHC titanium(III) complex 2 , respectively. They feature distorted trigonal bipyramidal geometries. Short intramolecular Cl···C NHC contacts are observed in the X‐ray single‐crystal structures of 1 and 2 .
