Asymmetric Oxygen Bridged Copper(II) Carboxylate: Synthesis, Complete Characterization, and Crystal Structure

Mononuclear vs. binuclear carboxylates of copper(II) with 2,2′‐bipyridine: Synthesis, characterization, structural description, and properties

“…The bridging bond lengths are quite asymmetrical where the axial one is 2.3305(14) Å, while the other one is 1.9485(15) Å. These and other Cu–O and Cu–N bond lengths and angles are comparable to those of para ‐methoxy phenyl acetate‐based copper(II) complex with 2,2′‐bipyridine . The striking difference in bridging bond lengths is responsible for the nearly perfect square pyramidal geometry around copper with a distortion factor (174.03(6) − 171.89(6)/60) = 0.03.…”

“…The striking difference in bridging bond lengths is responsible for the nearly perfect square pyramidal geometry around copper with a distortion factor (174.03(6) − 171.89(6)/60) = 0.03. Such asymmetric bonding was observed in a structural analogue with para ‐methoxy phenyl acetate ligand …”

“…There is one bipyridine unit attached to each copper ion of the dimer or two bipyridine ligands attached to each copper ion . The former category contains diverse bridging groups between copper ions such as hydroxyl and water, carboxylate, chloro‐, or mixed bridging groups . Carboxylate moiety exhibits diverse coordination and bridging modes in copper carboxylate complexes.…”

“…The distortion factor τ was calculated by the equation τ = β – α /60°, where β is the largest angle and α is the next major angle around the M II ion . The distortion factor τ values for complex ( 1 – 3 ) are 0.002, 0.20, and 0.21, respectively.…”

“…The distortion factor τ was calculated by the equation τ = βα/60°, where β is the largest angle and α is the next major angle around the M II ion. [16] The distortion factor τ values for complex (1-3) are 0.002, 0.20, and 0.21, respectively. In complexes 1 and 3, carboxylate of one 3,4-dichlorophenylactate molecule acts as uni-dentate ligand while carboxylate of the other 3,4-dichlorophenylactate molecule acts as didentate ligand and is attached in syn-syn position.…”
