Trans-[Cu(quin)2(EtOH)2] (1) was synthesized as part of our study on copper(II) quinaldinate complexes with various O- and N-donor ligands. Compound 1 characterized by infrared spectroscopy, thermal analysis X-ray structure analysis.

Soil microorganisms play important roles in nitrogen cycling within forest ecosystems. Current research has revealed that a wider variety of microorganisms, with unexpected diversity in their functions and phylogenies, are involved in the nitrogen cycle than previously thought, including nitrogen-fixing bacteria, ammonia-oxidizing bacteria and archaea, heterotrophic nitrifying microorganisms, a...

The presence of the additional heterocyclic nitrogen atoms in chiral P,N ligands has an important influence on the asymmetric catalysis, and a clear trend was observed in the present research that the enantioselectivity and reactivity were significantly increased by raising the number of heterocyclic nitrogen atoms in these P,N ligands. Through finely tuning the number of heterocyclic nitrogen ...

This report describes the synthesis and characterization of metal halide complexes (M = Mn, Fe, Co) supported by a new family of pendant donor-modified alpha-diimine ligands. The donor (N, O, P, S) substituent is linked to the alpha-diimine by a short hydrocarbon spacer forming a tridentate, mer-coordinating ligand structure. The tridentate ligands are assembled from monoimine precursors, the l...

(N(nBu)4)[MIIIL(acac)2], M = Y, Gd, Tb and Dy, have been constructed by combination of two O donor ligands, bidentate acetylacetone tetradentate p-tert-butylcalix[4]arene.

Supramolecular main group chemistry is a developing field which parallels the conventional domain of metallo-organic chemistry. Little explored building blocks in this area are metal-based ligands have appropriate donor symmetry to build desired molecular or extended arrangements. Tris(pyridyl) (E(py)3, E=main metal) potentially highly versatile since shifting N-donor arms from 2- 3-positions a...
