What is Thermal Stability and Absorption Spectroscopic Behavior of (μ-Peroxo)dicopper Complexes Regulated with Intramolecular Hydrogen Bonding Interactions about?

## Abstract In order to clarify the effect of hydrogen bonding on the stabilities of (μ‐peroxo)dicopper complexes with a __trans__‐μ‐1,2‐peroxo form, novel copper complexes with intramolecular hydrogen bonding interaction sites have been synthesized, and their spectroscopic properties and thermal stabilities studied. The selected tripodal tetradentate ligands were tris(2‐pyridylmethyl)amine (TPA) derivatives bearing pivalamido and amino groups at the 6‐position of the pyridine ring in TPA, {[6‐(pivalamido)pyrid‐2‐yl]methyl}bis(pyrid‐2‐ylmethyl)amine (MPPA) and [(6‐aminopyrid‐2‐yl)methyl]bis(pyrid‐2‐ylmethyl)amine (MAPA). The single‐crystal X‐ray structure of a monomeric Cu^II^ complex with N~3~^−^ namely [Cu(mppa)N~3~]ClO~4~ (1a), revealed an interligand hydrogen bonding interaction between the substituent NH group of MPPA and the azide nitrogen atom in the axial position. The Cu^I^ complexes of MPPA and MAPA were immediately oxygenated with dioxygen in acetone solution at −78 °C to give the μ‐peroxo dinuclear copper(II) complexes [{Cu(mppa)}~2~(O~2~)]^2+^ (1b) and [{Cu(mapa)}~2~(O~2~)]^2+^ (2b). These complexes exhibited two kinds of characteristic absorption bands (π\*~σ~⇄d~σ~, π
