Double chelate coordination of [Cu(Ph P) ] stabilizes the radical anion of 2,2'-azobis(5-chloropyrimidine), which exhibits a N-N bond length of 1.345(7) Å in the complex (see picture). This is consistent with a one-electron reduced azo functionality.
[Cu(Ph P) ]的双螯合配位作用使2,2'-偶氮双(5-氯嘧啶)的自由基阴离子得以稳定，该自由基阴离子在配合物中的N-N键长为1.345(7) Å（见图）。这与单电子还原的偶氮官能团相符。
