It's hip to be a square! The ammines [Li(NH3)4][Ind] and [Na(NH3)4][Ind] both contain a cation coordinated by four ammonia molecules. Whereas the first shows the anticipated tetrahedral coordination, in the second the metal coordination is unexpectedly square-planar. The solvent-separated ion pair forms a rippled layer structure of alternating planar Na(NH3)4+ cations and indenyl carbanions that is attributed to NH3⋅⋅⋅π hydrogen bonds.
