Single-crystal to single-crystal phase transitions of bis(N-phenylisonicotinamide)silver(i) nitrate reveal cooperativity properties in porous molecular materials

Two single-crystal to single-crystal phase transitions in trans-[Ag(NPI)(2)](NO(3)).2CH(3)OH (), (NPI = N-phenylisonicotinamide) were characterized with X-ray crystallography; the first transition is reversible and arises from a desolvation transition induced by vacuum and generated ; the second transition was induced by heat at 140 degrees C and generated .
