Rezumat

Heating of a pink two-dimensional Co(ii) coordination network {[Co₂(μ₂-OH₂)(bdc)₂(S-nia)₂(H₂O)(dmf)]·2(dmf)·(H₂O)}_n (1) built from 1,4-benzenedicarboxylic acid (H₂bdc) residues and thionicotinamide (S-nia) ligands initiates a single-crystal-to-single-crystal transition accompanied by removal of both coordinated and co-crystallized solvents. In the dry blue form, [Co(bdc)(S-nia)]_n (dry-1), the Co(ii) centers changed from an octahedral to a square pyramidal configuration.
