Xuanjun Zhang, Dan Li* and Xiao-Ping ZhouAbstract:Distinctly different 3D assemblies of B1.6 nm Au nanoparticles are constructed based on weak and strong coordination strategies. Reduction of KAuCl4 with NaBH4 in the presence of newlysynthesized 4-(4-phenylmethanethiol)-2,20:60,20 0-terpyridine (1) yields functionalized Au nanoparticles which assemble in situ into large 3D aggregates via weak coordination between alkali metal ions and terpyridine attached to separated particles. These assemblies

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

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

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

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

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
