Cu(II) complexes of 1-[4-(3-ethyl-piperidine-2,6-dione)-3-yl]-phenyl-2,4,6-trisubstituted pyridinium perchlorates, containing alkyl, aryl and combinations of these two types of moieties in their molecule were synthesized and characterized by elemental analysis, spectroscopy, magnetic, thermogravimetric and conductimetric measurements. In these complexes, Cu(II) ions are in octahedral geometry w...

Libraries of lanthanide complexes supported by nitrogen and oxygen containing ligands have been synthesised using a high-throughput approach. The complexes were employed in the ring-opening polymerisation of epsilon-caprolactone, in some cases giving polycaprolactone of controlled molecular weight and narrow polydispersity. The libraries, based on twenty-one ligands and eight lanthanide reagent...

This perspective summarizes the chemistry of platinum metal complexes of β-diiminate ligands bearing aryl groups at the nitrogen atoms. While β-diiminate ligands mostly coordinate in a κ(2)-N,N' mode, palladium complexes have a tendency to rearrange to C-bound structures (κ(2)-N,C or μ-N,N':C). Diiminate ligands are remarkably effective at stabilizing coordinatively unsaturated metal centers, a...

the objectives of this experiment were to investigate the application of new ligands including different atoms & evaluation their nucleophile effects against various metals. chemistry researchers are really interested in this field. from among various ligands, there are some ligands with different coordinating ligands as well. there are great number of intermediate complexes and major eleme...

The synthesis of copper and silver silyl complexes containing either N-heterocyclic carbenes or nitrogen donors is described. Alterations made to both the neutral donor ligands as well as the silyl group provided access to a number of different compounds. Many of the complexes synthesized were studied in the solid state and the effect of the donor ligand on the final structure of the complexes ...

An overview is given of the chemistry of tris(azolyl)phosphines with focus on their preparation and application in coordinationand organometallic chemistry and catalysis. These systems share with the more abundant tris(pyrazolyl)borates and -methanes the ability to function as tridentate nitrogen ligands with hemilabile character, but the additional phosphine donor site grants them bifunctional...

the interactions between platinum complexes and human serum albumin (hsa) play crucial roles in the distribution, metabolism, and activity of platinum-based anticancer drugs. octahedral platinum (iv) complexes represent a significant class of anticancer agents that display molecular pharmacological properties different from cisplatin. in this study, the interaction between two pt(iv) complexes ...

Four copper(II) complexes with the ligands bearing two or three alkylpyridine pendant arms attached to an ethylene diamine framework were isolated in pure form (four-coordinate species as perchlorates, and five-coordinate species as hexafluorophosphates). Three complexes and one tosylated ligand were characterized by X-ray diffraction. In the absence of additional monoor bidentate ligands, line...
