Nickel(II) complex of p-[N,N-bis(2-chloroethyl)amino]benzaldehyde-4-methyl thiosemicarbazone: Synthesis, structural characterization and biological application

Synthesis of some transition metal complexes of novel 1-methylpyrazole-3-aldehyde-4-(2-pyridyl) thiosemicarbazone: Spectroscopic and in vitro biological activity studies

“…Always n → π* transitions occurs at a lower energy than π → π* transitions [40]. In the spectra of M(II) complexes the bands observed in the region 26521-26920 cm -1 are assigned to S→M charge-transfer band [41]. The bands in the range 30870-31108 cm -1 observed in the spectra of all M(II) complexes are assigned as Cl → M charge-transfer transitions [42].…”

“…Always n → π* transitions occurs at a lower energy than π → π* transitions [44]. In the spectra of Ni(II) complexes the bands observed in the region 25321-25603 cm -1 are assigned to S → Ni charge-transfer band [45]. The bands in the range 30870-31108 cm -1 observed in the spectra of all Ni(II) complexes are assigned as Cl → Ni charge-transfer transitions [46].…”

Thermal, spectral, DFT and biological activity evaluation of Co(II), Ni(II) and Cu(II) complexes of N,S-chelated benzotriazole ligand
