The involvement of two different alkali cations in the nonagermanide ammoniate Cs3.2Na0.8Ge9 center dot 5.3NH(3) [tricaesium sodium nonagermanide-ammonia (1/5.3)] provides insights into the coordination behaviour of ammonia towards sodium and caesium cations within one compound and represents the first mixed-cationic solvate structure of nonagermanide tetra-anions. The compound crystallizes in the monoclinic space group P2(1)/m and, with the presence of pseudomerohedral twinning, mixed-cation sites and disordering of the nonagermanide cage anions, features a combination of crystallographic challenges which could all be resolved during the refinement.
