A desktop means of estimating the distribution of charge among the ligands in an organometallic complex is developed. An iron charge state of cFe = +2.0 is chosen as a reference, and by correlation of ν(CO) with charge, cCO, in a set of carbonyl complexes, an equation of charge is generated. Application of this equation to the periodic table affords each transition metal a single charge, cM, thereby flipping the oxidation state formalism. Ensuing investigations of carbonyl/L/X compounds leads to estimates of charge distributions among classes of ligands. Deemed charge distribution via reporters (CDVR), the method provides a means of assessing the stability of ligand combinations about metal centers within seconds and numerically supports common pedagogical intuition.
