The coordination chemistry of guanidines and guanidinates

New Pr and Nd complexes containing TCNQ radicals

The cobalt(II), nickel(II) and zinc(II) complexes of diethyl (2-oxo-1-phenyl)ethylphosphonate 1 (compounds 2, 3 and 4, respectively) were synthesized using the corresponding metal halides. Their structure was studied by spectroscopic (IR, electronic and EPR) and magnetochemical methods. The experimental data indicate that the cobalt and nickel complexes (2 and 3, resp.) are octahedrally coordinated by the bidentate phosphonyl ligand, two of the coordination sites being occupied by H2O molecules. The 1H, 13C and 31P NMR data for the zinc complex 4 prove that the product is a mixture of (Z)-and (E)-isomers, with the (Z)-isomer being predominant.

Copper(II) Complexes with 1H-Indene-1,3(2H)-diones derivatives

Structure of six- and seven-membered cyclic- β-diketones and their metal(II) complexes

The cytotoxic properties of Monensic acid (MonH) and its biometal(II) complexes [M(Mon)2(H2O) 2] (M = Mg, Ca, Mn, Co, Ni, Zn) against the Gram-positive anaerobic bacterium Clostridium perfringens spp. are reported. All the studied Monensin complexes possess similar structures, but their activity varies in the concentration range from 0.17 μmol/L to 11.90 μmol/L Biometal(II) complexes improved the properties of Monensic acid in in vitro experiments, suggesting their possible practical application as more effective antibacterial agents than the non-coordinated antibiotic.
