Abstract
Correlating bond length, crystal structure and Phillips ionicity in simple binary compounds with covalent crystal radii shows that most oxides and some fluorides have to be regarded as covalent compounds with respect to their crystal radii. “Anomalous covalent” octahedral radii of oxygen and fluorine should be interpreted as ionic radii.
