IR spectrum of complex [Ni(HL8)L8]ClO4- 7H2O (o). The electronic spectral data of thiosemicarbazones and their Ni(II) complexes in DMF solution are summarized in Table 3.4 and the spectra are given in Figs 3.18 and 3.19. The intraligand electronic transitions of HL7 suffered considerable shift on coordination as evidenced by the absorptions obtained for 5. The band with the highest molar absorptivity at 20750 cm" is assigned as S—>Ni LMCT transition. The spin allowed transitions 3T2g(F)
Chapter 3 charge transfer bands. For compound 6 also the S—>Ni charge transfer band at 22470 cm" masks the possible d -d bands in that region. For compound 7 the CT band is obtained at 24150 cm", assigned S—>Ni LMCT. Another absorption obtained at 31250 cm" is assigned as n —> 71' * transition. For a diamagnetic Ni(II) complex, as a consequence of eight electrons being paired in the four low-lying d orbitals with the upper orbital being d ‘Z , _ the four lower orbitals are often so close in energy that - -y individual transitions from them to the upper d level cannot be distinguished resulting in a single absorption band. The shoulder band obtained at 193 80 cm" for 7 is attributed to the d -d band of this type. The d —d bands appearing as weak shoulders centered around the 20,000 cm" region are typical of square planar monoligated Ni(H) complexes [38]. Table 3.4.
