“…The Raman shift of the symmetric uranyl stretch for complex 3-t Bu was observed at 789 cm −1 (λ ex = 1064 cm −1 ; Figure S22). Similar symmetric and asymmetric stretching frequencies for uranyl complexes are observed in Schiff base ligand systems, including UO 2 (sal-p-phdn)(H 2 O) (υ asym = 915; υ sym = 830 cm −1 ) (sal-p-phdn = N,N′-p-phenylene-bis(salicylideneiminato)) 41 and UO 2 (NCS) 2 (Me-N-Sal) 3 Due to the bright blue colors of 3 and 3-t Bu, investigation by electronic absorption spectroscopy was also performed. Both complexes exhibit three strong absorbances in the UV−vis region ( Figure 5).…”

“…Anal. Calcd for C 41 (4). A 20 mL scintillation vial was charged with Cp*UO 2 ( Mes PDI Me ) (3) (0.100 g, 0.125 mmol) and 3 mL of toluene and cooled to −35°C.…”

“…These changes of the IR spectra suggest that L 1 , L 2 , L 3 are coordinated to the Zr(IV) via two nitrogen atoms of amino (N‐H) and hydrazono (C=N) groups. The ν(O‐H) vibration of the water molecules in the prepared complexes were found at 3397–3402 cm ‐1 also, the ν(C=O) was found at 1599–1615 cm −1 .…”

“…The infra‐red spectra for the three free ligands (L 1 , L 2 , L 3 ) and their metal complexes were showed in Figure S1 and listed in Table . From these spectra the site and kind of donation that may be involved in chelation could be identified . At 3413 and 1406 cm −1 two bands attributed to the stretching vibration of ν(N‐H) amino and for ν(C=N) hydrazono groups.…”
