Fig. 2. Perspective views of 1Pt·H2O at 187 K (structurally equivalent to 1Pd·H2O at 180 K) displaying (a) a bimetallic layer in the ⋯HS–LS⋯ ordered intermediate state representing in blue the LS Fe1 sites and in orange the HS Fe2 sites and (b) three stacked layers showing the planes containing the HS or LS sites (hydrogen atoms are omitted for clarity).
