phosphonitrilen.

Brit.

/ˌfɒsfə(ʊ)ˈnʌɪtrʌɪl/, U.S.

/ˌfɑsfoʊˈnaɪtrᵻl/,

/ˌfɑsfoʊˈnaɪˌtraɪl/

Origin: Formed within English, by compounding. Etymons: phospho- comb. form, nitrile n.

Etymology: < phospho- comb. form + nitrile n. Compare earlier phosphonitrilic adj.

Chemistry.

Any of a class of compounds containing a group ^_P≡N; a polymeric form of such a compound containing —^_P=N— groups. Cf. phosphazene n.

1921 J. R. Partington Text-bk. Inorg. Chem. xxxi. 625 At 175–200°, ammonia and phosphorus pentachloride form a mixture of six phosphonitrile chlorides: (PNCl₂)₃, (PNCl₂)₄, [etc.].

1943 Chem. Rev. 32 102 Most investigators have accepted the designation phosphonitrile for the PN group, since it is looked upon as a group resembling the CN or nitrile radical.

1972 H. R. Allcock Phosphorus-nitrogen Compounds i. 3 The cyclo- or polyphosphazenes (phosphonitriles) are probably the best known and most intensively studied phosphorus-nitrogen derivatives.

1991 Inorg. Chem. 30 4095/2 We have shown that the photolysis of phosphane azides led to transient phosphonitriles (R₂PN), which are in fact the monomeric units of polyphosphazenes.
