Abstract
The Cover Feature shows that the biochemical production of nitric oxide significantly affects various biological functions. For CrIIIL(ONO)2]+, a decrease in the CrIII−O with an increase of the CrIIIO−NO bond triggers NO delivery during excitation. There is also a significant change in the bond angle (Cr−O−NO) at S=3/2, enlarging the O−NO bond for the β-cleavage of NO. This reflects the energy difference observed between the low-spin doublet and high-spin quartet due to spin crossover (SCO). The pendant chromophore′s role in generating NO effectively enhances light absorption. More information can be found in the Research Article by J. Guadalupe Hernández and P. Thangarasu (DOI: 10.1002/cphc.202400700).
