The reaction of N,N′,N′′ ‐trimethyl‐1,3,5‐triazacyclohexane chromium trichloride ((Me 3 TAC)CrCl 3 , 1 ) with LiN(SiMe 3 ) 2 or NaN(SiMe 3 ) 2 in petroleum ether yields nearly quantitatively [Cr{N(SiMe 3 ) 2 } 3 ] ( 2 ) with loss of the Me 3 TAC ligand. Compound 2 could be crystallized from hexamethyldisilane as [Cr{N(SiMe 3 ) 2 } 3 ] · (Me 6 Si 2 ) 0,5 which allowed the refinement of the X‐ray crystal structure in the trigonal space group P‐31c (no. 163) ( a = 16.012(3) Å, c = 8.4796(12) Å, V = 1882.8(6) Å 3 , Z = 2) without severe disorder.
