It is even more difficult to find an earlier paper on a related structure,
again because of the uncertain stoichiometry of these mixed valence
compounds:
Modulated structure of the composite crystal Ca13.6 Sr0.4
COD does not have very sophisticated search options; if the exact formula
is not listed, it is difficult to find similar structures with slightly
different stoichiometry.
If instead you search ICSD :-) you will easily find:
Siegrist, T.;Schneemeyer, L.F.;Sunshine, S.A.;Waszczak, J.V.;Roth, R.S.
