Mixed ligand complexes of Iron(III) and Au(III) with succinimide or 8-hydroxyquinoline as primary ligands and amino acids as secondary ligands have been synthesized. The general formula of these complexes are follows: K[Fe(L)2(L′)2] & [Au(Q)( L′)] where L= C4H4O2N(1-5), Q= C9H6NO (6-10); L′=C6H12NO2 (1,9), C6H10N2O4S2(2,6), C3H6O2NS(3), C3H6NO3 (4,7), C9H10O2N (5,8). The complexes were prepared...

Vibrational circular dichroism (VCD) spectroscopy is a powerful tool to characterize absolute configurations and conformations of chiral organometallic systems. Such characterizations rely on the corresponding density functional theory (DFT) spectral simulations which may become very time consuming and sometimes even impossible for systems with increasing complexity. Systematic studies on small...

The preparation and characterization of four new copper(ii) complexes supported by click generated mixed NN, NO, and NS 1,2,3-triazoles are reported. The four complexes display a 1 : 2 copper/ligand ratio and give monomeric units in the solid state. Crystal structures demonstrate that depending on the flexibility of the ligand NX (X = O, N, S) pendant arm, the coordination environment around th...

Three new complexes of formulation fac-[Re(CO)3(diim)L], where diim is either 1,10-phenanthroline or 1,10-phenanthroline functionalised at position 5 by a thioalkyl chain, and L is either a chloro or aryltetrazolato ancillary ligand, were synthesised and photophysically characterised. The complexes exhibit phosphorescent emission with maxima around 600 nm, originating from triplet metal-to-liga...

A series of cobalt(ii) complexes of a highly electron-withdrawing amido ligand, [N(C6F5)(C6H3Pr(i)2-2,6)](-) (L), were synthesized and structurally characterized. Mononuclear [CoL(Cl)(TMEDA)] (3) and heterobimetallic [CoL2(μ-Cl)Li(THF)3] (4) were obtained by direct metathetical reactions of anhydrous CoCl2 with one molar equivalent of [LiL(TMEDA)] (1) (TMEDA = Me2NCH2CH2NMe2) and [LiL(THF)3] (2...

An anti-tumor compound as N3-{phenyl [(4-pyridylcarbonyl) amino] methyl} weresynthesized and identified (NPPA). Fe (III), Co(II) and Pd(II) metal complexes of this ligand preparedby reaction of chloride salt of Fe (III), Co(II) and Pd(II) with NPPA in dry acetonitrile. Identification andCharacterization of the ligand was performed by FT-IR, 1H-NMR spectroscopy and elemental an...

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...

Three new mixed Ni(II), Co(II) and Cu(II) complexes have been created using 2-((2-mercaptophenylimino)methyl)-4-methoxyphenol 1,10-phenanthroline. FT-IR, Elemental analysis, magnetic susceptibility, UV-Vis molar conductivity technique all used to explore the structural characterisation of these compounds. Magnetic susceptibility readings for L-Cu, L-Ni, L-Co were 1.97 BM, 2.92 2.84 respectively...
