Oxoperoxomolybdenum(VI) complexes of catalytic and biomedical relevance: Synthesis, characterization, antibacterial activity and 3D-molecular modeling of some oxoperoxomolybdenum(VI) chelates in mixed (O,O) coordination environment involving maltol and β-diketoenolates

Coordination Complexes of Manganese and Their Biomedical Applications

“…The enhancement in bacterial inhibition activity may depend upon the charge distribution, size, shape and redox potential of the metal complexes. Moreover, pharmacokinetic and steric factors also play a vital role in determining the potency of an antimicrobial agent . A complex C 59 , [Mn II ( a L 59 )( b L 59 )Cl] was prepared with 1,10‐phenanthroline ( a L 59 ) and a mono negative tridentate guaifenesin ligand ( b L 59 ) (OOO coordination sites).…”

Oxido- and mixed-ligand peroxido complexes of niobium(v) as potent phosphatase inhibitors and efficient catalysts for eco-friendly styrene epoxidation

“…68,70 Furthermore, shifting of the stretching vibration of the CvO group to a lower wavenumber of 1622 and 1638 cm −1 for 1 and 2, respectively, suggested the involvement of the carbonyl group in complexation. 50,[67][68][69][70] Similarly, in the case of complex 3, the coordination of niobium to deferiprone through the -OH and CvO groups was confirmed from the absence of the peak at 3147 cm −1 and shifting of the stretching vibration of the CvO group from 1630 to 1611 cm −1 in the complex. 54,71 In addition to the aforementioned frequencies, the presence of a sharp band at ca.…”

Material of oxo-peroxo-molybdenum (VI) complex involving 4-Furoyl-3-methyl-1-phenyl-2-pyrazoline-5- one: experimental cum theoretical observations

“…These observations agree with results reported elsewhere. 11,12 The experimental and theoretical FTIR spectrum are given in Figures 1 & 2, respectively. The electronic spectrum of a complex was recorded in a 10 -4 M DMSO solution.…”
