Popis:	Cu(II) complexes bearing N2/Py2 tetradentate ligands consisting of two pyridyl arms and a flexible ethyldiamine backbone, [(BPMEN)Cu(ClO4)2] (1), with rigid cyclohexyl backbone [(BPMCN)Cu(ClO4)2] (2), and substituted with bispyrrolidyl [(PDP)Cu(ClO4)2] (3), and Cu(II) complex bearing N2/Py3 pentadentate ligand, [(TPMEN)Cu(ClO4)2] (4), were synthesized and structurally characterized. Reactivity of 1–4 with cumyl hydroperoxide was investigated to study the effects of ligand rigidity and denticity on the mechanism of O–O bond cleavage. Results presented herein illustrate that 1–3 favors homolysis, however 4 showed little to almost no impact on O–O bond cleavage.
