Abstract
The first homoleptic imido compounds of transition metals, namely the imido analogues of the tungstate, WO4 2–, and perrhenate, ReO4 –, anions have been obtained as the lithium salts, Li2W(NBut)4and Li(tmed)Re(NBut)4; the structure of the tungsten compound contains two W(NBut)4 units linked by N Li N bridges while that of the rhenium compound shows the lithium co-ordinated to N atoms of tetramethylethylenediamine and to two N atoms of the anion.Keywords
