标题化合物由Ｌａ（ＮＯ３）３·ｎＨ２Ｏ,１,１０－邻菲罗啉（ｐｈｅｎ）和乙酰丙酮等在无水乙醇和水的混合溶剂中合成并用ＩＲ谱和Ｘ射线结构分析进行表征。晶体学数据如下：Ｃ２４ Ｈ２１ＬａＮ８Ｏ１４,Ｍｒ＝ ７８４．４０, 三斜, Ｐ１, ａ＝ ７．１２４（１）, ｂ＝ １１．０４７（２）, ｃ＝ １９．３９３（４）, α＝ ８１．１０（３）, β＝ ８７．７９（３）, γ＝ ７４．３６（３）°, Ｖ＝ １４５２．０（５）３, Ｚ＝ ２, Ｄｃ＝１．７９４ｇ／ｃｍ ３, Ｆ（０００）＝ ７８０, μ（ＭｏＫα）＝ １．５５７ｍ ｍ － １。化合物由阳离子〔ｐｈｅｎＨ〕＋ 和配合阴离子〔Ｌａ（ＮＯ３）４（Ｈ２Ｏ）（ｐｈｅｎ）〕－ 及一个结晶水分子组成。配合阴离子中以Ｌａ原子为中心,周围被２ 个Ｎ原子（来自ｐｈｅｎ）和９ 个Ｏ原子（来自ＮＯ３－ 和Ｈ２Ｏ）所占据,构成较为罕见的１１ 配位。晶胞中两两阳离子〔ｐｈｅｎＨ〕＋ 及两两配体ｐｈｅｎ 平面之间均相互平行堆积,并有多种类型的氢键存在,这些都可以降低能量,有利于化合物在晶体中的堆积。 相似文献

A new copper(II) complex [Cu2(DMF)(H2O)(C7H4NO4)2(C7H3NO4)]2·3.5DMF has been synthesized and its structure was determined by single-crystal X-ray diffraction.The crystal is of triclinic,space group P1 with a = 10.722(3),b = 18.170(4),c = 20.923(7),α = 105.297(9),β = 101.701(10),γ = 105.74(1)°,V = 3615(1) 3,Z = 2,C58.50H64.50Cu4N11.50O31.50,Mr = 1686.90,Dc = 1.550 g/cm3,μ = 1.255 mm-1,F(000) = 1728.00,T = 150(2) K,the final R = 0.0640 and wR = 0.173 for 11310 observed reflections with I > 2σ(I).In the crystal,each formular unit consists of two dinuclear copper(II) compounds,between which the O-H···O hydrogen bonds exist.Each CuII cation is six-coordinated in an octahedral geometry.The intermolecular hydrogen-bonding interaction leads to a 3-D framework of the title compound. 相似文献

1 INTRODUCTION Orotic acid (H3dtpc), an important pyrimidine derivative as the effective precursor in the biosynthesis of pyrimidine base of nucleic acids in living organisms, plays a unique role in bioinorganic and pharmaceutical. Aside from the biological interest, orotic acid is also interesting in coordination chemistry. Its ketonic and enolic tautomers along with asymmetric geometry make it to be a very good versatile polydentate ligand[1~5]. The incorporation of metals into supram… 相似文献
