Valence delocalisation in a strongly coupled (Kc = 1014) molecule-bridged cyanodiiron(III,II) species
Abstract
A hybrid between the Prussian Blue and Creutz–Taube mixed valent species is presented in the form of the bmtz-bridged bis[tetracyanoiron(+2.5)] complex 13– [bmtz = 3,6-bis(2-pyrimidyl)-1,2,4,5-tetrazine] which exhibits a very large comproportionation constant of 1014 and a delocalised structure, according to UV–VIS–NIR–IR spectroelectrochemistry in acetonitrile solution.
