Experimental and computational characterization of structural and spectroscopic features of mixed ligand copper complexes-prototypes for square-pyramidal stereochemistry

Triazine-based mononuclear copper(ii) cis-dichloro and dibromo complexes as functional biomimetic model systems for phenoxazinone synthase and catecholase activities

“…Unfortunately, the four-line hyperfine splitting due to the presence of 63 Cu ( I = 3/2) was not observed for 1 and 2 , and for square pyramidal Cu( ii ) complexes, similar literature reports exist. 64,65…”

“…The unpaired electron present in the d x 2 Ày 2 orbital of paramagnetic copper(II) metal center in all the square pyramidal complexes 1 and 2 is responsible for their four-line hyperfine splitting due to the presence of 63 Cu (I = 3/2) was not observed for 1 and 2, and for square pyramidal Cu(II) complexes, similar literature reports exist. 64,65 Catechol oxidase and phenoxazinone synthase activity…”

Mononuclear copper(ii) complexes with polypyridyl ligands: synthesis, characterization, DNA interactions/cleavages and in vitro cytotoxicity towards human cancer cells

“…Unfortunately, similar to literature reports, the four-line hyperfine splitting due to the presence of 63 Cu ( I = 3/2) was not observed in [ 1 ](ClO 4 ) 2 and [ 2 ](ClO 4 ) 2 . 67,68…”
