摘要
Solvothermal reaction of imidazolyl-based synthon with deprotonated adipic acid produced a new coordination complex {[Zn（BIDPE）(hdc)]·2 H;O}n（1）. The structure was characterized by single-crystal X-ray crystallography. It crystallizes in monoclinic, space group C2/m, at 293 K: a = 12.005（2）, b = 17.956（3）, c = 12.039（2） ?, β = 113.089（3）°, V = 2387.3（7） ?;, Z = 4, Dc = 1.524 g·cm-3, μ（Mo Ka） = 1.082 mm–1 and F（000） = 1136. 5942 reflections were measured and 2180 independent reflections（Rint = 0.0679） were used in further refinement. Complex 1 reveals 1D double-stranded chains containing [Zn;（BIDPE）;] and [Zn;（hdc）;] metallocyclic rings. The adjacent chains are linked by H-bonding and π···π interactions to form a 3D network. Thermal stability and luminescence property were studied. Interestingly, the luminescent emission of 1 can be quenched by the addition of trace amount of acetone, demonstrating its potential application for sensitive detecting acetone.
Solvothermal reaction of imidazolyl-based synthon with deprotonated adipic acid produced a new coordination complex {[Zn(BIDPE)(hdc)]·2 H_2O}n(1). The structure was characterized by single-crystal X-ray crystallography. It crystallizes in monoclinic, space group C2/m, at 293 K: a = 12.005(2), b = 17.956(3), c = 12.039(2) ?, β = 113.089(3)°, V = 2387.3(7) ?~3, Z = 4, Dc = 1.524 g·cm-3, μ(Mo Ka) = 1.082 mm–1 and F(000) = 1136. 5942 reflections were measured and 2180 independent reflections(Rint = 0.0679) were used in further refinement. Complex 1 reveals 1D double-stranded chains containing [Zn_2(BIDPE)_2] and [Zn_2(hdc)_2] metallocyclic rings. The adjacent chains are linked by H-bonding and π···π interactions to form a 3D network. Thermal stability and luminescence property were studied. Interestingly, the luminescent emission of 1 can be quenched by the addition of trace amount of acetone, demonstrating its potential application for sensitive detecting acetone.
