Carboxylate complexes Raman spectra

Carboxylate and Related Complexes. The FTIR spectrum of M(Nap)3 (phen), where M = Y, La, Eu, Tb or Dy HNap = a-naphthoic acid, includes bands from bidentate carboxylates.348 IR and Raman data for [Ln(2,6-dhb)5(H20)2]2, where Ln = Sm, Tb Hdhb = 2,6-dihydroxybenzoic acid, also reveal vC02 bands from bidentate carboxylates.349 vC=0 bands for homo-binuclear Ln3+ complexes of (65) linked by p-xylyl groups are seen in the range 1580-1600 cm-1, compared to 1690 cm-1 for the free ligand (Ln = Eu, Tb, Yb).350... 

The IR spectrum of Cu(stpy)2(0Ac)2(H20)2,where stpy = trans-4-styryl-pyridine, includes bands from unidentate acetato ligands. Raman and IR spectra of the copper complex CuL2, where HL = N-ethyl oxamate, EtH-NCOCOOH, are consistent with bidentate coordination, through C = 0 and a unidentate carboxylate. ...
