An air- and light-sensitive, but thermally stable tris[(trimethylsilyl)methyl]zirconium complex containing an NNNN-type macrocyclic ligand [Zr(Me3TACD)(CH2SiMe3)3] (1; Me3TACD = Me3[12]aneN4: 1,4,7-trimethyl-1,4,7,10-tetraazacyclododecane) was prepared by reacting [Zr(CH2SiMe3)4] with (Me3TACD)H. Reaction of the zirconium tris(alkyl) 1 with a Lewis or Brønsted acid gave a dialkyl cation with a weakly
