| Abstract: | Formation and Properties of Li2P7R (R = Si(CH3)3, CH3, C(CH3)3) The reaction of P7(Sime3)3 with Li3P7 in the molar ratio of 2:1 yields LiP7(Sime3)2, and in the molar ratio of 1:2 Li2P7Sime3 is formed. Li2P7me and Li2P7Cme3 (me = CH3) are obtained by reaction of white phosphorus with Lime, or LiCme3, respectively 2]. The compounds Li2P7R (R = Sime3, Cme3, me) show typical valence tautomerism, as established by 31P-n.m.r. spectroscopy at various temperatures. Also LiP(Sime3)2 transforms P7(Sime3)3 to yield Li2P7Sime3 but in this reaction considerable cleavage of P? P bonds occurs, too. |
