Magnetic properties of some copper(II) complexes of N-salicylideneamino acids and N-2-hydroxy naphthylideneamino acids

Synthesis and spectroscopic properties of [N-(4-carboxyphenyl) salicylideneiminato] di- and tri-organotin (IV) complexes and crystal structures of {[nBu2Sn(2-OHC6H4CHNC6H4COO)]2O}2 and Ph3Sn(2-OHC6H4CHNC6H4COO)

“…The infrared spectra of all the ten complexes show strong typical broad bands at 3387-3431 cm À1 related to the phenolic hydrogen stretching vibration according to the previous report [21], which strongly indicates that in the complexes the phenolic oxygen atoms do not participate in coordination to the tin atoms. The bands appearing at 1608-1624 cm À1 for all the complexes can be assigned as m(C@N) vibration according to the previous reports [22][23][24] show that the amino nitrogen atoms are not participating in coordination to the tin atom.…”

Antibacterial Activity of Pd(II) Complexes with Salicylaldehyde-Amino Acids Schiff Bases Ligands

“…1) UV-VIS Spectra The electronic spectra of the Pd(II) complexes exhibit bands in the UV range at 275-280 nm and ), correspond to the ν (C=N) stretching vibration. [18][19][20] Further, the shift observed for ν asym (COO Table 3.…”

Complexes with diastereoisomeric ligands. 1. Copper(II) complexes with the tridentate Schiff bases of (1R)-3-(hydroxymethylene)camphor or (1R)-2-(hydroxymethylene)methone and (S)- or (R)-amino acids

“…They were prepared according to the method reported in the literature. 20 The phenylalaninatocopper(II) compound was dried by azeotropic distillation with benzene.…”
