“…S16 and S17†), with analogies to previous reports on ATI-bound NO 2 and phenyl groups acting as Lewis bases towards alkali metal ions. 20,43 The distortion of the coordination polyhedra can be traced back to the small bite angle of the ATI ligand ( 2-Li-py : N1–Li1–N2, 76.7(3)°, 2-K-thf : N1–K1–N2, 58.43°). The Li1–N1/2 and Li1–O bond lengths of 2-Li-py (Li–N, 2.03 Å; Li–O 1.96 Å) are within limits of error identical to those of the parent compound [Li–ATI iPr/iPr (thf) 2 ] (Li–N, 1.99–2.00 Å; Li–O, 1.96–1.97 Å).…”
