Spectroscopic and DFT study of atenolol and metoprolol and their copper complexes

Contrasting mechanisms of metoprolol uptake on kaolinite and talc

“…6) of crystalline MT matched well with the published results [5,7,8,9]. The peak assignments were listed in Table 1.…”

“…6). The presence of aliphatic -CH may be confirmed by the stretching vibration at 2960-2850 cm À1 [5,8,9]. In contrast, the 2980 and 2872 cm À1 region was associated with the m(NH 2 ) and m(NH) modes [7].…”

Hybrid nanoadsorbents for the magnetically assisted removal of metoprolol from water

“…1515 cm -1 , that can be ascribed to the symmetric bending of N-H in MTP [52]. Further evidences of the presence of MTP are the bands due to aliphatic C-H stretching, in the region of 2870-2950 cm -1 , that become more marked after adsorption and the appearance of a weak shoulder at 1585 cm -1 , ascribed to the C-C stretching of the aromatic ring [53].…”

Synthesis, spectroscopic, thermal, electrical conductivity and antimicrobial interpretations of new VO(II), Zn(II), Pd(II), Au(III) and Pt(IV) complexes with hypertensive atenolol drug

“…This fact can be explained by taking into account the intermolecular HB effects which are expected to have an important blue-shifting effect on this band and most probably, it is contained in the broad peak centered at1639 cm -1 in the IR spectrum. This supposition is sustained by the observed IR peak in the spectrum of metoprolol, another b-blocker with a similar structure to atenolol but without amide groups, at 1634 cm -1 that can be safely assigned tó (NH) mode since this molecule does not contain the carbonyl group 47 . In comparison with the published spectra [47][48][49][50][51][52] of the free ATN spectra (Fig.…”

“…The different method techniques adapted to the analysis of Atenolol have been reported [28][29][30][31][32][33][34] . However, Literature survey reveals that there is no attempt has been made to study the complexation of ATN by transition metals except copper [35][36][37][38] . Sodium atenolol dithiocarbamate (ADTC) and its complexes with copper, nickel, zinc, cobalt and cadmium have been synthesized 39 .…”
