EPR study of the low-spin [d(3); S =(1)/(2)], Jahn-Teller-active, dinitrogen complex of a molybdenum trisamidoamine. Academic Article uri icon


  • The first EPR study of the trisamidoamine complex, [Mo]N2, where [Mo] = Mo(III)[HIPTN3N] and HIPT = [3,5-(2,4,6-i-Pr3-C6H2)2C6H3NCH2CH2]3N3-, reveals that this low-spin (S = 1/2) [d3] complex exhibits a 2E state that undergoes a pseudo Jahn-Teller distortion in the adiabatic limit, modified by interactions with the solvent, and analysis gives approximate values of interaction energies. The experiments establish that [Mo]N2 exhibits the low-spin [e3] electronic configuration, not [a2e1], with the a(z2) antibonding orbital substantially higher in energy than the e[xz, yz] orbitals.
