Thioether S-ligation in a side-on -2:2-peroxodicopper(II) complex

Ga Young Park, Yunho Lee, Dong-Heon Lee, Julia S. Woertink, Amy A. Narducci Sarjeant, Edward I. Solomon and Kenneth D. Karlin

[(ANS)CuI(CH3CN)]+ reacts with O2 giving [{(ANS)CuII}2(-2:2-O22-)]2+, O–O = 731 cm-1, shown to possess S-thioether ligation, based on comparisons with analogues having all N-ligands or a –S(Ph) group. The finding is a rare occurrence and new for side-on O22- binding.
