A new complex [Zn(4-nph)(bib)]_(2n)·nH_2O(1) has been obtained by the reaction of metal(Zn(Ⅱ)),1,4-bis(imidazol-1-yl)-butane(bib) with 4-nitrophthalic acid(4-H_(2nph)).The crystal structure of 1 has been determined by single-crystal X-ray diffraction analysis.Compound 1 is of triclinic system,space group P1 with a = 10.3251,b = 12.4503,c = 16.6497 ?,α = 88.487(3),β = 72.529(3),γ = 79.991(3)°,V = 2009.8(5) ?~3 and Mr = 945.47.Complex 1 shows a three-dimensional(3 D) framework.Moreover,through intermolecular hydrogen bonds,compound 1 is assembled into a supramolecular structure.The thermal stability and luminescent properties of 1 are also investigated. 相似文献

利用推广的粒子—转子模型研究了奇 A 核的电四极跃迁几率 B(E2)的 signatute 依赖性随费米能λ的变化特征。指出在Υ(?)0时,当费米面从高 j 壳的底部向顶部移动时,[B(E~2;△I=1)/B(E~2;△I=2)]~1/2比值的 signature 依赖性逐渐消失,核心的十六极形变、二级柯里奥利作用对 E_2跃迁的影响同费米面的位置有关. 相似文献

A new complex has been synthesized by the reaction of CuBr and 1,4-bis(2-allyl-2 H-tetrazol-5-yl)benzene. The crystal structure of the resulting complex, [Cu_3(1,4-bis(2-allyl-2 H-tetrazol-5-yl)benzene)Br_3]_n(1), has been determined by single-crystal X-ray diffraction analysis. Complex 1 is of monoclinic system, space group P21/c with a = 10.983(7), b = 6.294(4), c = 17.606(10) ?, β = 102.465(6)°, V = 1188.4(3) ?~3 and Mr = 577.52. Structural analyses revealed complex 1 shows a three-dimensional(3 D) framework. The thermal stability and luminescent properties of the complex are also investigated. 相似文献

利用轴对称超形变和三轴超形变模型研究了165Luπ[6601/2]带两种模型计算的γ跃迁能量都能较好地符合实验值,然而,能量的signature颤动指数、三轴因子、两类动力学电四极矩之比却存在明显的差别,这些差别可以用来识别三轴超形变核态 相似文献

利用16O重离子束轰击142Nd和147Sm同位素靶分别生成153Er和157Yb.借助氦喷嘴带传输系统和X-γ、γ-γ符合测量方法分离鉴别核素并测量其衰变性质.首次建立了153Er和157Yb的EC/β+衰变纲图.从中指认出153Ho的一个新三(准)粒子态和两个新单粒子态,指认出157Tm的一个新的同质异能态和一条新转动带.低位能级系统分析表明:在Ho和Tm这两条奇A核的同位素链中基态形状的转变区都在中子数86和88之间. 相似文献
