DEFINITION

Classification: 514/102

Two or more phosphorus atoms directly or indirectly bonded together by only covalent bonds:

(under subclass 75) Subject matter in which the organo-phosphorus compound contains at least two nonionically bonded phosphorus atoms.

(1) Note. Organic phosphorus salts and complexes of a phosphorus containing compound and other compounds are excluded unless the phosphorus containing moiety has at least two nonionically bonded phosphorus atoms, e.g., [figure] [caption], etc.
