The cationic zinc complex [L1Zn][Al(OC(CF3)3)4] (1) (L1 = {[(2,4,6‐Me3–C6H2)NC(Me)]2CH}) bearing a weakly coordinating aluminate anion was obtained from reaction of L1ZnCl with Li[Al(OC(CF3)3)4]. In addition, base‐stabilized zinc cations [L1/2Zn(base)2][X] (2–5) (L2 = {[(2,6‐iPr2–C6H3)NC(Me)]2CH}; X = [Al(OC(CF3)3)4], [B(C6F5)4]) containing weakly coordinating anions and different Lewis bases (dimethylaminopyridine (dmap), tert‐butylpyridine (tBuPy)) were synthesized and structurally characterized. Moreover, the solid‐state structures of L1ZnMe (6) and the neutral base‐stabilized complexes tBuPy‐Zn(Cl)L1 (7) and base‐Zn(Me)L2 (base = dmap 8, tBuPy 9) are reported and compared with those of 25. Preliminary studies showed that 1 is catalytically activity in lactide polymerization at 160 °C.
