摘要
Hydrothermal reaction of 1H-tetrazolate-5-ethyl acetate (Htzea), MCl2 (M = Zn, Cd) and NaOH at different reaction temperatures produced three new coordination polymers: 2-D layered polymer [Zn(tza)(H2O)(2)](n) 1, and 1-D chained supramolecular isomers 2 and 3 formulated as [Cd(tza)(H2O)(2)](n) (H(2)tza = 1H-tetrazolate-5-acetic acid), respectively. In these obtained polymers, tza(2-) ligand adopts variable coordination modes: mu(3)-kappa N3:kappa O1:kappa O2,N1 and mu(3)-kappa N1:kappa N3:kappa O2 for 1, and mu(3)-kappa N2:kappa N1,O2:kappa O1,O2 for 2 and 3. The effects of reaction temperature and metal centers on the final polymeric frameworks have been discussed. Polymers 1-3 exhibit blue photoluminescence mainly arising from intraligand transitions of tetrazolate rings in tza(2-) ligand. (C) 2009 Elsevier B.V. All rights reserved.
