The full three-dimensional structure of Ag-intercalated molybdenum disulfide has been experimentally determined. The atomic pair distribution function (PDF) analysis technique has been employed because of the very limited structural coherence in this

Open framework metal chalcogenide solids, with pore sizes in the nano- and mesoscale, are of potentially broad technological and fundamental interest in research areas ranging from optoelectronics to the physics of quantum confinement1,2. Although th

New compounds in the system RE-Al-Ge (RE=Tb, Gd, Ho) were prepared in molten aluminum. Large, (up to 5 mm) single crystals of new pseudo-binary phases GdAl3−xGex, (x=0.1), TbAl3−xGex, (x=0.3), and HoAl3−xGex, (x=0.2) were recovered in high yiel

The polymerization of [Ge 4 S 10 ] 4− and [Ge 4 Se 10 ] 4− unit clusters with the divalent metal ions Zn 2+ , Cd 2+ , Hg 2+ , Ni 2+ , and Co 2+ in the presence of various surfactant cations leads to novel mesostructured phases. The surfactants ar

The discovery of MCM-41 and its relatives has spawned a revolution in the design and synthesis of tailored mesostructured oxide-based materials. By comparison, non-oxidic solids such as sulfides or selenides are only very little exploredÐpartly beca

In a search for inorganic oxide materials showing second-order nonlinear optical (NLO) susceptibility, we investigated several borates, silicates, and a phosphate containing trans -connected M O 6 octahedral chains or M O 5 square pyramids, where M =

The novel sulfidic mesophase [C14H29N(CH3)3]2MnGe4S10 forms via the surfactant-templated assembly of adamantane Ge4S104- clusters and Mn2+ ions in water. The material possesses a continuous, fully bonded framework of MnGe4S10 which is perforated with

We describe in this paper the synthesis and characterization of a new layered phosphate, MoOPO4·2H2O (I), and its intercalation chemistry. The phosphate I, crystallizing in a tetragonal structure (a = 6.375(7), c = 7.80(1) A, and Z = 2) similar to t

Several transition metal phosphates of the general formula $KM_{0.5}M'_{0.5}OPO_4$, where $M = Nb^v$ or $Ta^v$ and $M' = Ti^{III}, V^{III}, Cr^{III}, Fe^{III}$, possessing the $KTiOPO_4$ (KTP) structure have been synthesized. Unlike KTP, none of thes
