Two luminescent d10 metal coordination polymers assembled from a semirigid terpyridyl carboxylate ligand with high selective detecting of Cu2+, Cr2O72- and acetone

Two Zn(II) coordination polymers based on 4′-(4-carboxyphenyl)−4,2′:6′,4″- terpyridine have been obtained. Compound 1 shows high selective detecting for Cu2+ ion and acetone molecule. Meaningwhile, compound 2 shows highly selective sensitivity for Cr2O72−.249
