Potassium hydride reacts with HSC6H2Pr3i-2,4,6 (HSR) in THF or thf-tme
n (tmen = N,N,N',N'-tetramethylethylenediamine) to afford the first di
screte, hexameric potassium thiolates [{K(SR)}(2){K(thf)(SR)}(2){K(thf
>(2)(SR)}(2)] 3 and [{K(SR)}(2){K(thf)(SR)}(2){K(tmen)(SR)}(2)], 4 thf
, exhibiting an unusual box-shaped structure with three different coor
dination spheres for the three independent potassium atoms.
