Anion-Directed Assembly of Macrocycle and Helix
23次浏览
Xuanjun Zhang, Xiao-Ping Zhou, and Dan Li*Abstract:Self-assembly of the flexible ligand N,N¢-bis(3-pyridylmethyl)thiourea (bpt) with ZnCl2 and CdCl2 in the absence and presence of KSCN yielded a short series of novel complexes (1-4) with macrocyclic, helical, double-helical, and 1D polymeric structures. Different metal ions, hydrogen bonds, and counteranions play significant roles in the final crystal structures. The NCSanion was found to favor the formation of helical structures, whereas the Cl

Cu(I) or Cu(I)-Cu(II) Mixed-Valence Complexes of 2,4,6-Tri(2-pyridyl)-1,3,5-triazine: Syntheses, Structures, and Theoretical Study of the Hydrolytic Reaction Mechanism

Xiao-Ping Zhou, Dan Li,* Shao-Liang Zheng, Xuanjun Zhang, and Tao WuAbstract:The reactions of 2,4,6-tri(2-pyridyl)-1,3,5-triazine (tpt) with copper(I) halides under solvothermal or traditional conditions yielded two polymeric Cu(I) complexes [Cu2I2(tpt)]n (1) and [Cu3I3(tpt)]n (2), one mixed-valence Cu(I)-Cu(II) complex [Cu4Cl2I4(tpt)2] (3), and two Cu(II) complexes [CuBr(bpca)] (4) and [CuI(bpca)] (5) (bpca ) bis(2-pyridylcarbonyl)-amine). Complex 1 is a zigzag chain with tpt in a bis-bipyridin

Syntheses of supramolecular CuCN complexes by decomposing CuSCN: a general route to CuCN coordination polymers?
29次浏览
Xiao-Ping Zhou, Dan Li,* Tao Wu and Xuanjun ZhangAbstract:The solvothermal reaction of CuSCN with 1,2-bis(diphenylphosphino)ethane (dppe) yielded a coordination polymer, which was characterized to be a complex of CuCN and 1,2- bis(diphenylthiophosphinyl)ethane (dppeS2): [(CuCN)2(dppeS2)]n (1). The identification of complex 1 reveals that CuSCN was decomposed and the sulfur was transferred to dppe, and represents a new example of the transformation of inorganic sulfur to organic sulfur. The weak

Assembly of Large Aromatic Selenoether Ligands into Cubic and Non-interpenetrated (10, 3)-a Nets
27次浏览
Guo Huang, Hanhui Xu, Xiao-Ping Zhou, Zhengtao Xu,* Kunhao Li, Matthias Zeller, and Allen D. HunterAbstract:This paper reports on the strong tendency of a group of thioether and selenoether molecules to adopt non-centrosymmetric and non-interpenetrating features in forming 3D coordination networks with metal ions. We illustrate such tendency with the (10, 3)-a nets formed by Ag(I) ions and the large aromatic ligands of 1,3,6,8-tetrakis(phenylseleno)pyrene (TPhSeP) and 2,3,6,7,10,11-hexakis(pheny

Metal-Directed Supramolecular Architectures: From Mononuclear to 3D Frameworks Based on In Situ Tetrazole Ligand Synthesis
27次浏览
Zhen Li, Mian Li, Xiao-Ping Zhou, Tao Wu, Dan Li,* and Seik Weng NgAbstract:This work focuses on the investigation of the influence of metal ions and supramolecular interactions on the selfassembly of in situ generated tetrazolate coordination architectures. A series of new metal-organic complexes, [Zn(pzta)2(H2O)2](1), [Cu(pzta)2](H2O)3 (2), [Cd(pzta)2]n (3), [Ag(pzta)]n (4), and [Cd2(pzta)(OH)(SO4)]n (5) [pzta ) pyrazinyl tetrazolate], have been achieved by the in situ hydrothermal reactions o

pH-Induced formation of metalloligand: increasing structure dimensionality by tuning number of ligand functional sites
21次浏览
Wen-Xiu Ni, Mian Li, Xiao-Ping Zhou, Zhen Li, Xiao-Chun Huang and Dan Li*Abstract:Two complexes, 2D [Cu2(CN)2(4-Hpcih)]n and 3D{[Cu2(CN)1.5(4-pcih)]?1.25H2O}n (4-Hpcih = 4-pyridinecarbaldehyde isonicotinoyl hydrazone), were obtained using a synthetic approach of pH-induced formation of metalloligands, successfully demonstrating a strategy to increase structuredimensionality by tuning the number of ligand functional sites.文章链接：b705603f.pdf
