Infrared band assignments of the nickel(II) complex of glycine
Abstract
The i.r. spectra of trans-[Ni(gly)2(H2O)2](gly = glycinate anion) and its 18O-, 15N-, 1-13C-, and 2-13C-labelled analogues were measured in the 150–4 000 cm–1 region. The effects of isotopic substitutions indicate the need for revision of certain assignments of internal ligand vibrations and allow the assignment of the nickel–ligand vibrations.
