The compound contains the complex ion [Fe(CN)6]3-, which has the systematic name hexacyanoferrate(III). The potassium cations are written in front of the complex ion in the formula, indicating that they are simply counterions and do not contribute to the systematic name. Therefore, the correct name is potassium hexacyanoferrate(III).
