Phosphonium salt should probably merged here – compare ammonium salt and sulfonium salt. However, I'm not sure how to deal with the langlinks of Phosphonium salt; at least two of them (de, nl) refer specifically to quaternary phosphonium compounds, and only dewiki has separate articles on quaternary phosphonium salts and phosphonium anions (substituted and unsubstituted in one article). --ἀνυπόδητος (talk) 18:22, 8 November 2016 (UTC)[reply]
