摘要
Presented here is a new heterometallic Cu(I)-Sr(Ⅱ) coordination polymer, [Cu(3)Sr_2(isonic)_5 Br_2(H_2O)_3]n·n(H_2O)(1, Hisonic = isonicotinic acid), has been synthesized via the hydrothermal reactions of CuBr, Sr(NO_3)_2 and isonicotinic acid. The crystal structure is of triclinic system, space group P1 with a = 7.111(2), b = 14.934(4), c = 18.0255(11) ?, α = 83.137(15), β = 87.155(15), γ = 79.75(2)°, V = 1869.4(8) ?~3, C_(30)H_(29)Br_2Cu(3)N_5O_(14)Sr_2, Mr = 1209.27, Z = 2, Dc = 2.148 g/cm^3, F(000) = 1178, μ = 6.725 mm^(-1), R = 0.0500 and wR = 0.1008 for 4688 observed reflections(I > 2s(I)). Single-crystal X-ray diffraction analysis revealed that compound 1 features a 3 D heterometallic framework stabilized by bifunctional isonic ligands. In addition, the luminescent and photocatalytic properties of compound 1 were also investigated at room temperature.
