Stacks of platinum clusters display trigonal geometry in clusters of this molecule named for Paolo Chini. The UV-vis spectra of reduced cytochrome P450 enzymes bound to this molecule typically display a 450-nanometer Soret peak. The vibrational frequency of a complex containing this molecule measures a ligand’s (15[1])Tolman electronic parameter. Coordination of iodine and this molecule to iridium forms a complex (15[1])used to catalyze the synthesis of (*) acetic acid. This molecule, which is iso·electronic to cyanide, is listed furthest (-5[1])to the strong-field (-5[1])side (10[1])on the spectrochemical series. (10[1])Compared to another molecule, this heteroatomic molecule displays a 200-fold (10[1])higher affinity to hemoglobin. (10[1])For (10[1])10 points, name this poisonous, odorless gas formed during incomplete combustion. (10[1])■END■ (10[1])
