The crystal structure of the title compound, poly[[(4,7,13,16,21,24-hexaoxa-1,10-diazabicyclo[8.8.8]hexacosane)rubidium] [[(1,4,7,10,13,16-hexaoxacyclooctadecane)rubidium]di-mu-rubidium-mu-nonastannide] pentaammonia], {[Rb(C18H36N2O6)][Rb3Sn9(C12H24O6)C12H24O6)]center dot 5NH(3)}(n) represents the first ammoniate of a Zintl anion together with two different chelating substances, namely 18-crown-6 and [2.2.2]-cryptand. The involvement of these large molecules in the crystal structure of [Rb(18-crown-6)][Rb([2.2.2]-cryptand)]Rb2Sn9 center dot 5NH(3) leads to the formation of a new structural motif, namely one-dimensionally extended double strands running parallel to [100] and built by Sn-9(4-) cages and Rb+ cations. The double strands are shielded by 18-crown-6 and [2.2.2]-cryptand. The cations are additionally coordinated by ammonia molecules. One of the four independent Rb+ cations is disordered over two sets of sites in a 0.74 (2):0.26 (2) ratio.
