摘要
Solvates of triphenylmethyl potassium have been prepared with three different Lewis bases and their crystal structures determined by X-ray diffraction methods. In [KCPh(3)(PMDTA)] (1) (PMDTA = N,N,N',N'',N''-pentamethyl-diethylenetriamine) discrete molecules are observed whereas the solvates with DIGLYME (MeOCH(2)CH(2)OCH(2)CH(2)OMe) and THF are polymeric in the crystal: [KCPh(3)(DIGLYME)](n) (2, zigzag-chain structure) [KCPh(3)(THF)](n) (3, sheet structure).
