Syntheses and crystal structures of [K(2.2.2-cryptand)](2)[(mu-O){mu-O2Si(CH3)(2)}(2)(GeSe)(2)] and [K(2.2.2-cryptand)](2)[Sb2Se6]
[K(2.2.2-cryptand)](2)[(mu O){mu O2Si(CH3}(2)(GeSe)(2)] (1) forms from the adventitious reaction of silicone grease with the residue (dissolved in CH3CN) from the reduction of GeSe2 by K in NH3(l) in the presence of 2.2.2-cryptand. Reduction of SbSe under similar conditions leads to the isolation of [K(2.2.2-cryptand)](2)-[Sb2Se6] (2).
