Bathocuproine is a derivative of 1,10-phenanthroline with two methyl groups and two phenyl groups in the 2,9 and 4,7 positions, respectively. Like 1,10-phenanthroline, bathocuproine is a bidentate chelating ligand. The two methyl groups flank the nitrogen centers, such that bathocuproine is a bulky ligand. This compound, first prepared by Case and Brennan in the early 1950s ^[1]^[2] is a pale yellow solid that is soluble in polar organic solvents.^[3]
