Abstract
MPHTipp (M = K, Rb; Tipp = 2,4,6-Pri 3C6H2), prepared from potassium or rubidium and PH2Tipp in toluene heated to reflux, crystallises from THF/pentane as [{K(THF)2(PHTipp)K(THF)(μ-THF)(PHTipp)}x]2 (1) and [Rb(THF)(PHTipp)]x (2). The K salt shows a novel helical arrangement of K and P atoms in which THF molecules bridge two helices, while the Rb salt exhibits a ladder-type arrangement of Rb and P atoms.Keywords
