Metal (II) Complexes of Fluconazole: Thermal, XRD and Cytotoxicity Studies

We report thermal, X-ray diffraction (XRD) and cytotoxicity studies of complexes of fluconazole (FCZ) with Cu (II), Fe(II), Cd(II), Co(II), Ni(II), and Mn(II). From XRD measurements, FCZ and its metal complexes were identified as polycrystalline. Marked differences in the X-ray patterns of drug and its metal complexes revealed that the complexes are indeed different compounds and not just the m...

The electron density analysis of Cr(CO)3L complexes (L=benzene and graphyne)

h6-benzne, h6-garphyne) was studied with MPW1PW91 quantum chemical computations. Quantumtheory of atoms in molecules (QTAIM) was applied to elucidate these complexes Cr-CO bonds. Theellipticity (e) and h values of the Cr-CO bonds were calculated. The amount of pp-dp back-donation ofCr-CO bonds were illustrated by calculation of the magnitude of the quadrupole polarization of c...

Crystallographic Studies of Metal-Peptide Complexes

A violet-pink complex may be crystallized at high pH from a solution containing Cu2+ ions and the pentapeptide, tetraglycylglycine. A three-dimensional x-ray crystal structure analysis has shown that the complex is disodium tetraglycylglycinatocuprate(I1) 4.5-hydrate, NaJCu(NH2(CH2CON)~CHzCONHCHzC00)]~4.5H20. The crystals are triclinic, a = 7.306 A, b = 10.902 A, c = 12.012 A, a = 91.73”, 0 = 1...
