Spontaneous resolution of a [capital Delta]/[capital Lambda]-chiral-at-metal pseudo-tetrahedral Schiff-base zinc complex to a racemic conglomerate with C-H[middle dot][middle dot][middle dot]O organized 41- and 43-helices

03-Jul-2018 | Mohammed Enamullah; Vera Vasylyeva; Mohammed Abdul Quddus; Mohammad Khairul Islam; Simon-Patrick Höfert; Chris ..., CrystEngComm, 2018

The Schiff-base ligand, N-2-(pyridyl)salicylaldimine (HL) reacts with zinc(II) acetate or nitrate to give the enantiomorphous chiral-at-metal compound Δ/Λ-bis[N-2-(pyridyl)salicylaldiminato-κ2N,O]zinc(II), [Zn(L)2] (1), which crystallizes as a racemic conglomerate via spontaneous resolution. Two ...

Tailoring the morphology of Co-doped MoS2 for enhanced hydrodeoxygenation performance of p-cresol

03-Jul-2018 | Wenjing Song; Tianming Nie; Weikun Lai; Weimin Yang; Xingmao Jiang, CrystEngComm, 2018

A morphology tailoring strategy for the synthesis of Co-doped MoS2 nanostructures was realized through simply tuning the alkaline solutions in a solvothermal sulfidation reaction. The as-prepared Co-doped MoS2 nanoflowers exhibited an excellent p-cresol hydrodeoxygenation performance, which could ...

DNA assisted synthesis of CeO2 nanocrystals with enhanced peroxidase-like activity

27-Jun-2018 | Meng Wang; Mei-Fang Wang; Yi-Ming Wang; Jiwei Shen; Zhiying Wang; Han Gao; Li-Li Wang; Xiangyuan Ouyang, CrystEngComm, 2018

A series of CeO2 nanocrystals with different sizes have been synthesized with DNA as the template by hydrothermal synthesis method. The peroxidase-like activity of CeO2 nanocrystals was found to be strongly enhanced by DNA doping.

Two Lanthanide Metal–Organic Frameworks Constructed by Tris(4-carboxyphenyl)phosphane Oxide with Gas Adsorption and Magnetic Properties

26-Jun-2018 | Tuoping Hu; Qian-Nan Zhao; Liangqin Huo; Lingling Gao; Jie Zhang; xiaoqing wang; Liming Fan, CrystEngComm, 2018

Two lanthanide metal-organic frameworks (LOFs), namely, {[Eu(L3-)(H2O)]•5H2O}n (1), and {[Dy(L3-) (H2O)]•2CH3CN}n (2) have been synthesized based on tris(4-carboxyphenyl)phosphane oxide (H3L) and further characterized by powder X-ray diffraction (PXRD), IR spectra, elemental analyses and ...

Hydrogen bonding versus [small pi]-interactions: their key competition in sildenafil solvates

26-Jun-2018 | Rafael Barbas; Rafel Prohens; Merce Font-Bardia; Antonio Bauza; Antonio Frontera, CrystEngComm, 2018

Herein we report the X-ray characterization of four sildenafil solvates where the conformation of the pyrazolo[3,4-d]pyrimidine and phenyl rings depends on the solvent. It conditions the formation of an apparently innocent intramolecular H-bond that has a remarkable influence on the solid state ...

Synthesis of hollow ZnSe nanospheres with high photocatalytic activity: synergetic effect of cation exchange and selective Cu2-xSe template etching

26-Jun-2018 | Xin Huang; Yu Zou; Jian Hao; Jiang Jiang, CrystEngComm, 2018

Uniform ZnSe hollow nanospheres in face-centered cubic structure were synthesized via a postsynthetic chemical transformation reaction from solid Cu2-xSe nanocrystals, with the help of tributylphosphine at room temperature under ambient atmosphere. The formation of ZnSe hollow structure was based ...

Make full use of the synthesis cavity to synthesize the larger diamond single crystals under high pressure and high temperature

26-Jun-2018 | Yong Li; Yadong Li; Ying Wang; Jie Zhang; Mousheng Song; Xiaozhou Chen; Yanchao She, CrystEngComm, 2018

In order to make full use of the synthesis cavity and improve the production efficiency, we designed the double seed beds method to synthesize the larger diamond crystals under high pressure and high temperature (HPHT) conditions, which was both theoretically calculated and verified by ...

Two interpenetrated metal-organic frameworks with a slim ethynyl-based ligand: designed for selective gas adsorption and structural tuning

26-Jun-2018 | Xiang-Jing Kong; Yongzheng Zhang; Tao He; Xue-Qian Wu; Ming-Ming Xu; Si-Nan Wang; Lin-Hua Xie; Jian-Rong Jeff Li, CrystEngComm, 2018

In the design and construction of metal-organic frameworks (MOFs), the utilization of slim ligands is usually more inclined to form interpenetrated structures compared with bulky ones. The structural interpenetration can improve the framework stability, and in some cases enhance gas adsorption ...

A Two-fold Interpenetrated Zinc-Organic Framework: Luminescent Detection of CrO42-/Cr2O72- and Chemical Conversion of CO2

26-Jun-2018 | Ying Shi; Tian-Qun Song; Chun-Shuai Cao; Bin Zhao, CrystEngComm, 2018

A novel two-fold interpenetrated 3D metal-organic framework {[Zn(DCTP)]∙3.5H2O}n (1) (H2DCTP = 4'-(3,5-dicarboxyphenyl)-4,2':6',4''-terpyridine) was synthesized by pyridine-carboxylic ligand and Zn(OAc)2 under solvothermal conditions. Along the a-axis, a large pore exists in 1 with the size of ...
