A layered effect: Replacement of pyrazine (A) with Co- or Ni-coordinated 2-pyrazinecarboxylate (pzc; B) between neutral AgReO4 layers (red and blue polyhedra) yields M(pzc)2(H2O)2AgReO4 (M=Co (shown) or Ni). This novel strategy is aimed at pillared solids with coordinated H2O that can be reversibly removed without causing structural collapse to give coordinatively unsaturated Ni and Co sites.
