“…To identify the bonding mode as well as the complexation behavior of the prepared SBL and its metal complexes, the FT-IR spectral characteristics were recorded for SBL and its metal complexes. For 2,3-diaminopyridine, the characteristic vibrational peaks were reported at 3390, 3309, 2883, 1637, 1577, 1184, 1120, and 1064 cm −1 corresponding to N-H asymmetric stretching, N-H symmetric stretching, C-H aromatic symmetric stretching, N-H stretching of the pyridine ring, C=C stretching, C-N stretching, C-H in-plane bending, and C-O stretching, respectively 48 . Moreover, the anthracene-9-carbaldehyde characteristic vibrational peaks were reported at 2924–2854, 1682, and 1120 cm −1 corresponding to aromatic C-H stretching, C=O stretching, and C=C aromatic ring stretching, respectively.…”

A Schiff base ligand (SBL), N2, N3-bis (anthracen-9-ylmethylene) pyridine-2, 3-diamine, was synthesized through the condensation of 2,6-diaminopyridine and anthracene-9-carbaldehyde using a 1:2 ratio. 1H NMR spectra confirmed the observation of non-involvement aromatic carboxylic proton in SBL. A novel series of lanthanide (i.e., praseodymium (Pr), erbium (Er), and ytterbium (Yb))-based SBL metal complexes was successfully synthesized, and their functional groups were elaborately demonstrated using UV–visible, Fourier transform infrared (FT-IR), and fluorescence spectroscopy analyses. FT-IR spectral studies revealed that SBL behaved as a bidentate ligand and it was structured with metal ions by the two azomethine nitrogens. The synthesized SBL-based metal complexes were elaborately performed for cytotoxicity activity versus Vero, human breast cancer (MCF7), and cervical (HeLa) anticancer cell lines.

In this study, synthesis of two new tetracyanocadmate(II) and tetracyanozincate(II) complexes based on 3-aminopyridine (3AP) and investigation of their structural properties were reported. These complexes were characterized by using vibration spectroscopy, elemental, thermal analysis and single crystal X-ray diffraction (SC-XRD) techniques. Investigation of the elemental, spectral and single crystal data of these complexes showed that the formulas [Cd(3AP) 2 Zn(μ 4 -CN) 4 ] n ( 1 ) and [Cd(3AP) 2 Cd(μ 4 -CN) 4 ] n ( 2 ) fully explained their crystal structure. General information about the structural and chemical properties of these complexes obtained in single crystal form was obtained by observing the changes in the characteristic peaks of the 3AP with the [Zn(μ 4 -CN) 4 ] 2- and [Cd(μ 4 -CN) 4 ] 2- structures that make up these complexes. The behaviors of these complexes against changes in temperature were obtained by examining the temperature-dependent changes of their mass. The asymmetric unit of the heterometallic complexes 1 and 2 consist of half Cd(II) ion, half M ion [M = Zn1 in 1 and Cd2 in 2 ], two cyanide ligands and one 3AP.
