Fig. 5. Synthesis of CN–Y(NHAr*)2 (3) (top) and structure from single crystal X-ray diffraction (thermal ellipsoids at 50%), where Ar is 2,4,6-(iPr)3C6H2. (bottom) Hydrogen atoms on the carbon atoms and solvent molecules in the crystal lattice are not shown for clarity. Selected bond distances (Å) and angles (°): Y1–N1: 2.348(2), Y1–N2: 2.221(2), Y1–N3: 2.221(2), C1–N1: 1.039(4), Y1–N1–C1: 170.4(2)°.
