    • An iron-cobalt heterobimetallic dinitrogen complex LFeNNCoL is also accessible, though it has not been crystallographically characterized. Its 1H NMR spectrum is consistent with two inequivalent diketiminate environments. An N-N stretching vibration is present in the IR spectrum at 1806 cm-1 1743 cm-1 with 15N2, The N-N stretching mode is not observed in infrared spectra of LFeNNFeL or LCoNNCoL, and the observation of an infrared-active N-N band is strong evidence for the heterobimetallic complex LFeNNCoL. See the Supporting Information for characterization of this and other compounds
