Chapter 5 5.3.3. IR and electronic spectral studies The IR spectra of manganese complexes show marginal differences from their corresponding ligands. The IR spectral assignments of the Mn(H) complexes are listed in Table 5.1. The square complex 19 shows both C=S and C—S stretching bands suggesting the presence of both thione and thiolate coordination. Absence of bands at ~ 2600 cm" for 19 and 20 are indicative of absence of of thiol tautomers in free or coordinated form in these complexes [40]. Similarly, the carbohydrazone grid complexes 21, 22 and 23 show both C=O and C-0 stretching bands. These are in agreement with other results. The change in frequencies for assigned bands and differences in mixing patterns of common group frequencies of complexes compared to their respective metal free ligands are attributed to the coordination to metal center. The spectra in the far IR region is also rich with bands attributable to coordination of pyridyl N, azomethine N and sulfur/oxygen to Mn(lI). The sulfur metal coordination is supported by strong bands at 350 and.354 cm" for complexes 19 and 20, assigned to v(Mn-S). The v(Mn-Nm) and v(Mn-Npy/qu) frequencies for all the complexes are seen at ~420 and ~280 cm" respectively. For 21, 22 and 23, clear indication of ionic form of perchlorate is seen. The broad bands at 1100s, 1090s, 1100s cm" for 21, 22 and 23 respectively are attributed to v3(ClO4), while unsplit bands at 625 cm" for these three compounds are assigned to v4(ClO4). These indicate presence of ionic perchlorate species (T ,1 symmetry) [41]. The other bands at ~935 cm" for these compounds, assignable to v |(ClO4), are very week For the azido complex 20, a sharp band at 2058 and a strong band at 1294 cm" are assigned as asymmetric and symmetric stretching of coordinated azido group [42]. The weak band at 630 cm" may be of 5(NNN). The band at 324 cm" in the far IR region is attributed to v(Mn-Nam.) [42], also supporting the azide coordination to metal. Selected IR and far IR spectra are given in Figs. 5.11 to 5.15. 214
