delta points to sigma[edit]

Why is that? Is that a mistake? --Kupirijo 22:26, 29 March 2007 (UTC)

Suggested re-organization of article[edit]

This topic is large and complex but it might be worthwhile trying to reorganize it so that it emphasized the most significant species and distributed space vaguely in proportion to the "real world." One possible outline for the article:

  • Phosphorus(V) species: phosphine oxide (OPR3); phosphinate (OP(OR)R2); phosphonate (OP(OR)2R); Phosphate (OP(OR)3) (brief, since these are not really organophosphorus - or should we not worry about that formality?); phosphonium salts.
  • Phosphorus(III) species: phosphine (PH2-nRn, including PM2-nRn where M = Li, Na); phosphinites (P(OR)R2); phosphonite (P(OR)2R); brief mention of phosphites (P(OR)3) (brief since these are not really organophosphorus - or again should we not worry about that formality?)
  • Phosphorus(I) species: mainly (PR)n and RP=PR
  • Other mixed valence species (a potentially sprawling theme, which could get large)
for each of the above sections, we could include something on "related species," e.g. PXR2, X = NR2, Cl; and EPR3 (E = S, NR)
for each of the sections above we could include subsections on "synthesis," "applications," and possibly "new developments" (to cover the researchy themes in the current article). Editors are welcome to disagree with the above or whatever.

coordination of phosphine oxides[edit]

In the text it says "Phosphine oxides (designation δ3λ3)". Is this correct? Shouldn't it be δ4λ5? --kupirijo (talk) 00:25, 9 March 2011 (UTC)

Missing information[edit]

Why no discussion re bond lengths? Or differences in bond lengths? Swfowkes (talk) 00:19, 31 October 2012 (UTC)

Because we are waiting for editors like you to contribute! Try it. --Smokefoot (talk) 02:27, 31 October 2012 (UTC)
