A Zinc Complex Based on 4-Bromoisophthalic Acid and 1,2-Bi(4-pyridyl)ethane: Hydrothermal Synthesis, Crystal Structure, and Fluorescent Properties

摘要

A novel zinc complex formulated as [Zn(Bript)(bpa)(H₂O)]_n (1) (H₂Bript = 4-bromoisophthalic acid, bpa = 1,2-bi(4-pyridyl)ethane) has been synthesized through hydrothermal reaction. It was structurally characterized by elemental analysis and x-ray single-crystal diffraction. The x-ray crystal structure shows that the complex belongs to monoclinic systems, P2₁ space group, and a = 10.997(6) ? , b = 14.578(8) ? , c = 12.963(7) ? , ?2 = 105.993(6)?°. The adjacent Zn atoms are bridged by Bript to form a one-dimensional (1D) chain. Such 1D chains are further connected by hydrogen bonding to generate a three-dimensional (3D) supramolecular network. Fluorescence measurements show that 1 has medium fluorescent emissions at 404 nm and 468 nm upon excitation at 288 nm.View full textDownload full textKeywords1, 2-bi(4-pyridyl)ethane, 4-bromoisophthalic acid, crystal structure, fluorescent propertiesRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/15533174.2011.594838
