γ-Brasses with I and P cells

“…Nevertheless we have established without doubt that In4Ag 9 has a primitive cubic cell rather than a b.c. cubic cell suggested by earlier work (Hellner & Laves, 1947;Hellner, 1951) and we have shown that the ordering is similar to that in AlaCu 9 with In in A IT and B CO. We do not, however, feel that the accuracy of the structure determination justifies full publication of atomic coordinates, interatomic distances and structure factors, although these are available from the authors on request. Instead, in Table 2, we show for comparison with In4Au 9 'approximate' values of atomic coordinates resulting from refinement on data with h + k + l even to Rw = 0.088 (see below).…”
