Extended Data Fig. 1: Characterization of three MI2(tmeda) complexes (M = Zn, Cd, Hg).
From: Programmable synthesis of atomically precise semiconductor artificial atoms

a, 1H NMR of the free tmeda ligand and three complexes in CDCl3. The satellite peaks in CdI2(tmeda) correspond to the coupling between 1H and 113Cd (J = 4 Hz). b, TGA measurements of the complexes.
