A new complex { [Cu（NIT4py）2（ip）]·6H2O }, （NIT4py=2-（4＂-pyridinyl）-4,4,5,5-tetra methylimidazoline-1-oxyl-3-oxide and ip = isophthalate dianion） has been synthesized and structurally characterized by X-ray diffraction. It crystallizes in orthorhombic, space group Cmcm with a = 25.161（3）, b =10.045（1）, c = 15.450（2） A°, C32H48N6O14CU, Mr = 804.30, V= 3904.8（8） ,A°^3, Z = 4, De = 1.368 g/cm^3, μ（MoKa） = 0.630 mm^-1, F（000） = 1692, the final R = 0.0326 and wR = 0.0787 for 1843 independent reflections with Rint = 0.0372. Each Cu（Ⅱ） ion is four-coordinated by two carboxylate oxygen atoms and two pyridyl-N atoms from NIT4py radicals to furnish a rhombus geometry. The central Cu（Ⅱ） ion is located at an inversion center and a crystallographic two-fold axis. Each isophthalate dianion binds two Cu（Ⅱ） ions in bis-monodentate mode, leading to a 1-D chain, a＇ these 1-D chains are further linked into a 2-D network via hydrogen-bonding interactions.

为了建立简便快速的猪流行性腹泻病毒(PEDV)荧光定量RT-qPCR检测方法,根据GenBank数据库公布的猪流行性腹泻病毒囊膜蛋白E基因,设计特异性引物和探针结合微芯片技术,建立微芯片荧光定量RT-qPCR检测方法。该方法除对PEDV检测为阳性外,对与其同源性较近的致病病毒的检测均为阴性;最低检测限为1 copies/μL,常规荧光RT-qPCR检测限为10 copies/μL。批内、批间重复性试验表明,Ct值变异系数均在2%以内,可对PEDV临床样本进行检测。建立的检测方法特异性好、敏感性高、检测时间短且重复性好,适用于临床检测。
