Synthesis, characterization and spectroscopic and electrochemical studies of new axially coordinated cobalt(III) salen (salen=N,N′-bis(salicylidene)-1,2-ethylenediamine) complexes. The crystal structure of [CoIII(salen)(aniline)2]ClO4

N,N′-Dipyridoxyl(1,8-diamino-3,6-dioxaoctane) Schiff-base: Synthesis, experimental and theoretical identification

“…For comparison, some structural parameters of the similar compounds are listed in Table 1. The DFT structural parameters of H 2 L are in agreement with the structural data reported for the similar Schiff-bases [1,2,[10][11][12][13][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40], confirming validity of the optimized geometry for the H 2 L Schiff-base. The optimized geometry of the H 2 L with atom labelling is shown in Figure 1.…”

“…The selected DFT vibrational frequencies of the H 2 L are listed in Table 3. The vibrational modes were analyzed by comparing the previously reported data [28,[30][31][32] with the present work.…”

Synthesis, experimental and theoretical characterization of N,N′-dipyridoxyl (1,4-butanediamine) Schiff-base ligand and its Cu(II) complex

“…The vibrational modes were analyzed by comparing the data obtained from the literature reports [42][43][44][45][46][47] with the results of DFT calculations. Theoretical analysis of the IR and NMR spectra is an important tool to ensure the suitability of the proposed structures and identification of compounds [36,48].…”

Synthesis, crystal structures, electrochemically studies and antibacterial properties of three new mono-nuclear and one very rare bi-nuclear cobalt(III) Schiff base complexes

“…DNA binding studies and cobalt complexes have been investigated for their anticancer properties [18,19]. Cobalt(III) complexes have also been tested as hypoxia-activated anti-cancer prodrugs [20][21][22] and they are useful as catalysts for various asymmetric reactions [23]. Little attention has been paid to systems that contain Co(III) Schiff complexes [24][25][26].…”
