“…This is the situation for both investigated compounds in the present paper. On the other hand, G < 3.0 indicates strong exchange coupling and the observed g-values not reflect the individual Cu(II) molecular geometry [56].…”

“…Ratio which is defined as exchange interaction term specifies the ground state of the uncoupled electron 29 . The R value of the title compound is 2,81 and this value shows strong exchange coupling due to the reason given to in 30 . The covalency parameter of the complex ( ′2 ) is 0.54 that indicates that the unpaired electron expends 54% of its time on the d orbitals of the transition metal.…”

Compound based on the [Cu (oda)(hydet-en)] (oda=dianion of oxydiacetic acid, hydet-en=[N-(2-hydroxyethyl)-ethylenediamine]) has been synthesized and characterized by various spectroscopic methods (IR, UV-Vis, EPR) and thermal analysis (TG/DTG/DTA). Copper complex with mix ligands was determinated by single crystal Xray diffraction [oda] 2anion bridges Cu(II) ion with a bidentate coordination mode through its oxygen atoms of carboxylate groups. Single crystal X-ray data of the complex shows that the monomeric structure forms supramolecular frameworks with H-bonding. The FT-IR investigation of the complex was performed within the mid-IR region, mainly focusing on the characteristic (COO)as and (COO)s stretching vibrations of oxydiacetic acid. The powder electron paramagnetic resonance spectra of Cu(II) complex at RT was recorded. The results of EPR and UV-Vis spectra agree with the X-ray diffraction data.

Cu^II Complex of a 1,10‐Phenanthroline‐Based Pincer as an Efficient Catalyst for Oxidative Cross Dehydrogenative Coupling of Carboxylic Acids with Unactivated Alkanes

Synthesis of a well‐defined CuII complex 1 featuring a phenanthroline‐based tridentate scaffold, 2‐pyrazol‐(1,10‐phenanthroline) (L) and studies of its catalytic activity in the cross dehydrogenative coupling of acids with common alkanes to form allylic esters are reported. The complex 1 showed excellent catalytic activity in the oxidative cross dehydrogenative coupling of a wide variety of alkanes with acids to form the corresponding allylic esters in moderate to high yields. Several control experiments along with spectroscopic studies were carried out to characterize catalyst 1 and to explore the plausible mechanistic pathways.
