Syntheses, Crystal Structures and Luminescent Properties of Two Zinc(II) Coordination Polymers Constructed from Ether-Bridged Tricarboxylic Acid

Abstract

Two 1D zinc(II) coordination polymers, namely [Zn(mu-Hcpta)(4,4'-bipy)(H2O)](n) (1) and {[Zn-3(mu(3)-dbba)(2) (phen)(3)]center dot 6H(2)O}(n) (2), have been constructed hydrothermally using two ether-bridged tricarboxylic acids: 2-(4-carboxylphenoxy)terephthalic acid (H(3)cpta) and 2-(3,5-dicarboxylatobenzyloxy)benzoic acid (H(3)dbba), 4,4'-bipyridine (4,4'-bipy), 1,10-phenanthroline (phen) and zinc chloride. Single-crystal X-ray diffraction analyses revealed that two complexes crystallize in the monoclinic system, space groups P2(1) or I2. Complexes 1 and 2 show two different 1D chain structures.
