A variety of structures are shown in the solid state by the phosphanides MPHR of alkali metals. Whereas oligomeric and polymeric ladder or helical structures based on M–P bonds predominate for compounds of the lighter homologues (M=Li, Na, K), the 2,6‐dimesitylphenylphosphanides of Rb and Cs are present as a Rb 4 P 4 cubane and a Cs + {Cs 2 (PHR) 3 } − contact ion pair, respectively (the partial structures are shown above). These unexpected new structures show interactions between the metal center and π electrons of the ligand.
