摘要:
A new complex, namely bis[4′-(furan-2-yl)-2,2′:6′,2′′-Terpyridine]nickel(II) dichloride decahydrate, [Ni(C19H13N3O)2]Cl2·10H2O, has been crystallized by solvent evaporation and characterized by single-crystal X-ray diffraction. The coordination environment of the NiII cation is distorted octahedral with slight deviations from an idealized geometry. The most intriguing structural feature is an infinite two-dimensional hybrid water-chloride network parallel to (011) constructed by O-H⋯O and O-H⋯Cl hydrogen bonds involving two independent chloride ions and ten independent solvent water molecules with an l-shaped pattern. One of the furyl rings is disordered with a refined occupancy ratio of 0.786 (13):0.214 (13) © 2017.

摘要:
配位化合物[ Co( NH3)5 Cl] Cl2的制备是大学无机化学课程中一个重要的无机合成实验,但按照教材中的步骤进行操作,不但产率低、易生成其它副产物,而且HCl和NH3气体的挥发容易造成大气污染;同时,目标配合物的检测会造成大量贵重试剂AgNO3的浪费。基于绿色化学理念,针对教材中“一种Co( III)配合物的制备”相关的关键步骤和药品用量进行了改进和创新,节省了AgNO3试剂的用量,提高了产品的产率和纯度,同时也达到了环保的效果。

摘要:
A copper nanostructures-graphene oxide (Cu/GO) hybrid as a new electrocatalyst for highly sensitive detection of 2-naphthol (2-NAP) was successfully synthesized by a one-pot and in situ chemical reduction approach. The characterization results reveal that the cubic Cu nanostructures are tightly attached onto the GO sheets in the resulting hybrid. A lower oxidation potential and a larger peak current were observed for the 2-NAP oxidation at the Cu/GO modified electrode, demonstrating the synergistic electrocatalysis from Cu nanostructures and GO sheets. Consequently, the Cu/GO hybrid exhibits a low detection limit (5.0 nM) and wide linear ranges (0.1-4.0 mu M and 4.0-130.0 mu M) when used as a sensing material for the sensitive detection of 2-NAP. Finally, the fabricated sensor was successfully applied in the detection of 2-NAP in real samples and satisfactory recoveries in the range of 99.3%-104.0% were achieved. (C) 2014 Elsevier Ltd.

摘要:
Two coordination complexes [Cu(phtpy)(obda)]center dot 2H(2)O (1) and [Cu-4(meophtpy)(4)(mbda)(4)]center dot 4H(2)O (2) [phtpy = 4'-phenyl-2,2':6',2aEuro(3)-terpyridine, meophtpy = 4'-(4-methoxyphenyl)-2,2':6',2aEuro(3)-terpyridine, H(2)obda = 1,2-benzenedicarboxylic acid and H(2)mbda = 1,3-benzenedicarboxylic acid] have been synthesized under hydrothermal conditions and characterized by IR, elemental analysis and X-ray single-crystal diffraction. In complex 1, the Cu(II) atoms are bridged by obda(2-) ligands to give 1D chains with phtpy as a terminal ligand, while a 3D network is constructed by hydrogen bonds and pi-pi interactions. In complex 2, the Cu(II) atoms are coordinated by two meophtpy ligands and also linked by mbda(2-) ligands forming a discrete tetranuclear complex. In this complex also, a 3D network is constructed by hydrogen bonds and pi-pi interactions. The most striking feature of complex 2 is that one meophtpy ligand is almost overlapped upon the next which is seldom found in 2,2':6',2aEuro(3)-terpyridine complexes. The luminescence properties of both complexes 1 and 2 have been investigated.

摘要:
以正硅酸乙酯为硅源、三嵌段聚合物P123为模板剂,采用水热-后合成方法制备三胺基改性的多孔二氧化硅(3N-SBA-15)吸附剂,对其结构进行表征,并考察了吸附时间、体系初始pH值、吸附剂用量和温度等因素对水溶液中Cd~(2+)吸附的影响.结果表明,三胺基改性可显著增强SBA-15对Cd~(2+)的吸附能力,在pH=4.5、40℃、反应时间90 min的条件下,最大吸附容量为1.05 mmol/g. Langmuir方程可较好地描述Cd~(2+)在3N-SBA-15上的吸附平衡,20, 30和40℃下最大吸附容量分别为0.93, 0.97和1.05 mmol/g;热力学参数表明此吸附过程为自发吸热过程.对其吸附机理和材料的再生也进行了探索.

摘要:
Two 3d-4f heteronuclear coordination polymers {[CuEu2 (INAIP)3 (HCOO)(H2O)3] . 3H2O}n (1) {[NiEu2 (INAIP)4(H2O)4]-4H2O}n(2) were obtained by solvothermal assembly of CuCl/NiSO4-7H2O and Eu(NO3)3·6H2O with the H2INAIP (5-(isonicotinamido)isophthalic acid) ligand. Both complex 1 and 2 crystallize in triclinic, space group P1. For 1: a=1.088 7(3) nm, b = 1.515 8 (4) nm, c = 1.564 4 (2) nm, V =2.333 2 (10) nm3, Z=2, Dc=1.955 g·cm−3, μ= 3.203 mm−1, F(000)=1 352, Rint=0.027, R1=0.050 5, wR2=0.130 9. a=1.013 4(3) nm, b = 1.083 6 (6) nm, c = 1.374 1 (2) nm, V=1.453 0 (9) nm3, Z=1, Dc=1.878 g-cm−3, /μ=2.554 mm−1, F(000)=818, Rint=0.045 8, R1=0.034 1, wR2=0.086 9 for 2. Single-crystal X-ray diffraction analysis revealed that each INAIP2− ligand uses its two carboxyl groups to connect two or three Eu(III) ions into 2D lanthanide bi-layer structure. Then the 2D layers are further connected by pyridyl groups to give a three-dimensional two-fold interpenetrated pillared-layer structure in 1 with sqc27 topology. While in complex 2, the Ni(II) bonds to the pyridyl group (N) and carboxylate group (O) linking the 2D lanthanide layer into a 3D framework. In addition, the luminescent properties of complexes 1 and 2 have been investigated, which showed the obviously red photoluminescence in them.
