A layered effect : Replacement of pyrazine ( A ) with Co‐ or Ni‐coordinated 2‐pyrazinecarboxylate (pzc; B ) between neutral AgReO 4 layers (red and blue polyhedra) yields M(pzc) 2 (H 2 O) 2 AgReO 4 (M=Co (shown) or Ni). This novel strategy is aimed at pillared solids with coordinated H 2 O that can be reversibly removed without causing structural collapse to give coordinatively unsaturated Ni and Co sites.
