title: Crystalline Na-Si(NN) derivatives [Si(NN)= Si((NCH2tBu)2C6H4-1,2)]: the silylenoid [Si(NN)OMe]-, the dianion [(NN)Si-Si(NN)]2-, and the radical anion c-[Si(NN)]3-.
abstract: Reactions of the silylene Si[(NCH2Bu(t))2C6H4-1,2], [Si(NN)], with NaOMe, excess Na or 1/3 Na yield the X-ray-characterised crystalline compounds [Na(micro-Si(NN)OMe)(THF)(OEt2)]2 (2b), [Na(THF)2Si(NN)]2 (3) and [Na(THF)4][(Si(NN))3-c] (4).
