The structure of the title compound, di--acetato-triaquadinitratodistrontium, is characterized by a band-like succession of alternating pairs comprising an Sr2+ cation and an acetate group along [101]. Two neighbouring strontium acetate bands are combined into sheets parallel to (010) by sharing a corner O atom of the SrO9 polyhedra and by two additional bonds to intermediate NO3 groups. The sheets, however, are linked only by three corresponding Sr-O bonds via a second NO3 group. The water molecules are ligands of the strontium cations and are further hydrogen bonded to the O atoms of the NO3 groups. The centricity of the structure is in accordance with the lack of piezo-electric properties.
