The description of polytypes
as commensurately modulated structures with different modulation vectors is
presented for the concentration polytypism appearing
in the solid solution of the CdIn2Se4 compound in the multinary system Cd-Cu-In-Se. The
crystal structure of the 4Q-Cd1-xCuxIn2Se4
polytype was determined.
Projections of the structure of CdIn2Se4
(space group P-42m): ideal structure onto the (a) XY and (b) YZ plane,
disordered structure onto the (c) XY
and (d) YZ plane.
