Syntheses and solid-state structures of [{K(THF)_2(PHTipp)-K(THF)(#mu#-THF)(PHTipp)}_x]_2 and [Rb(THF)(PHTipp)_x (Tipp=2,4,6-Pr_3~iC_6H_2)

摘要

MPHTipp (M=K,Rb; Tipp=2,4,6-Pr_3~iC_6H_2), prepared from potassium or rubidium and PH_2Tipp in toluene heated to reflux, crystallises from THF/pentane as [{K(THF)_2(PHTipp)K(THF)(#mu#-THF)(PHTipp)}_x]_2 (1) and [Rb(THF)(PHTipp)]_x 2). The K salt exhibits a ladder-type arrangement of Rb and P atoms.
