We report an air-stable diradical dication of chiral D(2)-symmetric conjoined bis[5]diazahelicene with unprecedented high spin (triplet) ground state, singlet triplet energy gap, ΔE(ST) = 0.3 kcal mol(−1). The diradical dication possesses closed-s

Copper nitrite reductase (NiR) is a homotrimeric enzyme, containing a T1 copper site, which transfers electrons to the T2 catalytic site, where nitrite is reduced by one electron to nitric oxide (NO2− + 2H+ + e− → NO + H2O).1–3 Recently a sid
