摘要
A new copper coordination polymer[Cu2I(C7H5N4)2]n(1)with the 3-(pyridin-2-yl)-1,2,4-triazole(Hpt)and copper iodide was synthesized.It crystallizes in the triclinic space group P1 with a=8.6380(9),b=9.2434(9),c=11.8588(12)A,α=99.5890(10)o,β=109.0990(10)o,γ=105.2800(10)o,V=829.25(15)A^3,Dc=2.180 g/cm3,Z=2,F(000)=522,GOOF=1.046,the final R=0.0245 and wR=0.0598.The crystal structure shows that two copper ions are bridged by twoμ2-η1:η0-3-(pyridin-2-yl)-1,2,4-triazole anions and two iodide ions.The coordination environments of the Cu ion are Cu(1)N5 and Cu(2)N2I2,giving distorted square pyramidal geometry and trigon pyramid geometry.The magnetic and fluorescent properties of 1 were studied.
A new copper coordination polymer [Cu2I（C7H5N4）2]n（1） with the 3-（pyridin-2-yl）-1,2,4-triazole（Hpt） and copper iodide was synthesized. It crystallizes in the triclinic space group P1 with a = 8.6380（9）, b = 9.2434（9）, c = 11.8588（12） ?, α = 99.5890（10）o, β = 109.0990（10）o, γ = 105.2800（10）o, V = 829.25（15） ?3, Dc = 2.180 g/cm3, Z = 2, F（000） = 522, GOOF = 1.046, the final R = 0.0245 and wR = 0.0598. The crystal structure shows that two copper ions are bridged by two μ2-η1:η0-3-（pyridin-2-yl）-1,2,4-triazole anions and two iodide ions. The coordination environments of the Cu ion are Cu（1）N5 and Cu（2）N2I2, giving distorted square pyramidal geometry and trigon pyramid geometry. The magnetic and fluorescent properties of 1 were studied.
