Two ladder-chain zinc coordination polymers were synthesized in aqueous or N,N-dimethylformamide (DMF) solution by use of adipic acid dihydrazide (adih) precursor: {[Zn2(H2aph)(pim)2]·4H2O}n (pim = pimelate, H2aph = adipic bis(2-picolinylidene)hydrazide) and {[Zn2(adih)3][NO3]4·2DMF}n. X-ray crystal structures of the polymers were determined and the lattice solvent removal was investigated. The structural, spectroscopic and thermogravimetric studies confirm reversible and irreversible transformation upon desolvation for the former and latter 1D chains, respectively. The details of the reversible dehydration and rehydration are revealed by powder X-ray structure elucidation of the desolvated phase and are corroborated by IR spectroscopy.
