“…The absence of stretching bands corresponding to ν as (OAc) and ν s (OAc) in the acetate metal complexes i and iv with L and the existence of ν 1 and ν 2 bands at 1532 cm −1 and 1399 cm −1 in complex i and 1523 cm −1 and 1411 cm −1 in complex iv, respectively, confirmed the non‐participation of acetate group in both complexes [43] . The nonexistence of ν 1 , ν 2 and ν 5 bands and the occurrence of a broad band at 1384 cm −1 in the IR spectra of complexes ii and v indicated the non‐involvement of nitrate group in complexation [44] . In the case of sulfate complexes iii and vi, the appearance of a single broadband in the region of 1109–1110 cm −1 confirmed the non‐involvement of sulfate in complex formation [45–47] …”
