Ni (salen) | C16H16N2NiO2 | CID 135442964 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.
Recrystallization of [N,N'-Ethylene-bis(salicylideneiminato)]-nickel(II) [Ni(salen)] has been carried out from a large selection of solvents. Crystals can be either solvent free or solvates. This study is based on X-ray crystal structure determinations, which include the redetermination of Ni(salen) at low-temperature, the finding of three new solvates of Ni(salen), that is, Ni(salen ...
The nature and structure of occupied and empty valence electronic states (molecular orbitals, MOs) of the [Ni(Salen)] molecular complex (NiO2N2C16H14) have been studied by X-ray photoemission and absorption spectroscopy combined with density functional theory (DFT) calculations. As a result, the composition
A metal salen complex is a coordination compound between a metal cation and a ligand derived from N, N ′-bis (salicylidene)ethylenediamine, commonly called salen. The classical example is salcomine, the complex with divalent cobalt Co2+, usually denoted as Co (salen). [1] These complexes are widely investigated as catalysts and enzyme mimics. [2][3] A square planar metal-salen complex. The ...
1. Introduction The salen type di-Schiff base complexes of transition metals are one of the most exhaustively studied topic in coordination chemistry [1]. Their interest stems from the ease with which they can be synthesized, their versatility and wide range of complexing ability.
A comparative study of the electronic structure of the salen ligand in the H[2] (Salen) molecule and the [Ni(Salen)] complex was performed using the experimental methods of XPS, UV PES, and NEXAFS spectroscopy along with DFT calculations. Significant ...
The Ni 2p spectrum of the freshly prepared polyNiMeOSalen (Figure 6a) contained two peaks at 872.1 and 854.98 eV, typical for Ni (salen) complexes, which were assigned to Ni 2p1/2 and Ni 2p3/2 [21].

Nickel oxide nanoparticles have been synthesized by thermal treatment of N, N ′- (bis (salicylidene)-ethylene-1,2-diamine)Nickel (II); [Ni (salen)]; as precursor which has been synthesized via two methods: [Ni (salen)] were obtained by solid state reaction in absence solvent and co-precipitation reaction in presence of propanol as solvent, respectively. Nickel oxide nanoparticles were ...
A wealth of M-SALEN complexes have been synthesized as potential catalysts, with Cr, Mn, Fe, Co ions ( 8, 9, 10). Nickel (II) complexes with polydentate ligands are of interest to bioinorganic chemists as possible models for the active site in the metalloenzyme (Ni, Fe)-dehydrogenase ( 11).
