Preparation and structural characterization of dioxane-coordinated alkali metal bis(trimethylsilyl)amides

Abstract

Unsolvated RbN(SiMe3)z (1) and CsN(SiMe3)z (2) have been prepared from rubidium and cesium metal respectively and excess hexamethyldisilazane. The molecular structures of the polymeric dioxane adducts NaN(SiMes) .C4HsO2 (3) and [MN(S~M~~)~~.~C~H~(4O, M~ ]=. ROb; .5, ~MC =~ CHs)~ haOveZ been determined by low-temperature single-crystal X-ray diffraction.
