Các tính toán lý thuyết chức năng mật độ (DFT) được thực hiện cho một tập hợp đại diện các cấu trúc năng lượng thấp của C60−n Si n heterofullerenes (n = 1, 2, 6, 12, 20, 24, 30) để điều tra tác động của việc doping silicon lên cấu trúc electron của fullerene. Kết quả cho thấy các tham số bảo vệ hóa học (CS) rất nhạy cảm với sự biến dạng cấu trúc do các nguyên tử silicon được doping giãn ra từ bề m...... hiện toàn bộ
A Mild Transamination Route to [EtGaNEt]6: A Twelve-Vertex Gallium-Nitrogen ClusterJournal of Cluster Science - - 2002
Bing Luo, Wayne L. Gladfelter
The reaction of [EtGa(NMe2)2]2 with neat, excess EtNH2 afforded a glassy solid whose IR spectrum did not exhibit any N–H absorptions and 1H NMR spectrum indicated the presence of more than one compound. Refluxing a toluene solution of this solid afforded the imido gallium compound, (EtGaNEt)6 (1), in 56% yield. Compound 1 crystallized in space group R¯3 with a hexagonal prismatic structure constru...... hiện toàn bộ

The title complex Cd/4-(phosphonomethyl) benzoic acid 4-HOOCC6H14CH2PO3(H3BCP) with 1,10-phenanthroline has been hydrothermally synthesized directly as [Cd3(BCP)2(phen)]·H2O 1 (phen = 1,10-phenanthroline). The crystal structure was determined by single-crystal X-ray diffraction with the following data: triclinic P-1. The complex is a two-dimensional layer structure. Interestingly, the one-dimensio...... hiện toàn bộ
Thermal Activation of Molecular Tungsten Halide Clusters with the Retention of an Octahedral Metal Framework and the Catalytic Dehydration of Alcohols to Olefins as a Solid Acid CatalystJournal of Cluster Science - Tập 18 - Trang 414-430 - 2006

When the molecular tungsten halide cluster (H3O)2[(W6Cl8)Cl6]·6H2O, with an octahedral metal framework, is heated to 50 and 150 °C in flowing helium gas, it changes into (H3O)2[(W6Cl8)Cl6] and [(W6Cl8)Cl4(H2O)2], respectively. Activation at 250 °C yields a poorly crystallized solid state cluster, [W6Cl8]Cl2Cl4/2, which exhibits catalytic activity for the dehydration of ethanol to yield ethylene an...... hiện toàn bộ
