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

Xiao-Ping Zhou, Xuanjun Zhang, Shi-Hong Lin, and Dan Li*Abstract:Reactions of AgX with 2,4,6-tri(2-pyridyl)-1,3,5-trazine (tpt) yielded three 3D highly symmetric isostructural coordination polymers (X ) ClO4 -, BF4-, and PF6-) and a dimer (X ) CF3COO-), respectively. In the coordination polymers, anion-ð interactions are found between the multiatomic anions and tpt ligands. Systematic variation including synthetic methods, ratios of reactants, and solvents provides synthetic evidence proving tha

Xiao-Ping Zhou, Wen-Xiu Ni, Shun-Ze Zhan, Jia Ni, Dan Li,*and Ye-Gao Yin*Abstract:Solvothermal reactions of CuSCN, metal (Mn2+, Fe2+, Co2+, Ni2+,Cu2+) sulfate, and terpyridine (2,2¢:6¢,2¢¢-terpyridine or 4¢-p-tolyl-2,2¢:6¢,2¢¢-terpyridine) in the presence of triphenylphosphine yielded a series of hybrid coordination compounds, in which in situ formed metal bis(terpyridine) complex cations are encapsulated by a 3D anionic network or entangled by 2D heartlike networks, forming encapsulation or pol

In Situ Formed Guanidinium Cations as Templates To Direct Fabrication of Honeycomb-like CuCN Networks
28次浏览
Shi-Hong Lin, Xiao-Ping Zhou, Dan Li,* and Seik Weng NgAbstract:The solvothermal reaction of CuSCN and 1,2-bis(diphenylphosphino)ethane (dppe) in mixed solvents acetonitrile/n-hexane/ (methanol or ethanol) gave a honeycomb-like guanidinium cyanocuprate [C(NH2)3)] · [Cu2(CN)3]. The in situ formed cations C(NH2)3+ act as templates to direct the formation of the CuCN network in which multiple weak N-H· · · · N/C hydrogen interactions potentially exist between the cations C(NH2)3+ and the {CuCN}6 ri

CuCN Pillars Induce Face-to-Face π-Overlap of Anthracene-Based
26次浏览
Yan-Qiong Sun, Chun-Kwan Tsang, Zhengtao Xu,*Guo Huang, Jun He, Xiao-Ping Zhou, Matthias Zeller, and Allen D. HunterAbstract:The large aromatic ligand 9,10-bis{[3,4-bis(methylthio)phenyl]ethynyl}anthracene (L) interacts with CuCN to form a 2D, fluorescent hybrid network, L· 2CuCN. Although the edge-to-face stacking between the organic π-electron systems prevails in the molecular crystal structure of L, the face-to-face stacking becomes more distinct in L· 2CuCN. A preliminary survey on similar h
