the growing surfaces with chiral molecules, as well as by determination of the signs of optical rotation, and the piezoelectric effect. We show that the (1 0 0) face, according to the X-ray coordinates given herein, is that face whose step edges run along the diagonal from lower right to upper left.

Synthesis, coordination chemistry, and metal complex reactivity

Mechanochemical synthesis of new coordination polymers with acetylenedicarboxylate as bridging ligand

have attracted the attention of scientists for a number of reasons including the creation of nanometer-sized spaces and the discovery of novel phenomena as well as commercial interests such as their application in gas separation, gas storage and heterogeneous catalysis. Recent activities in crystal engineering have provided several examples of MOMMs that have rigid open frameworks, and therefore have the potential to be functionally related to zeolites. MOMMs often have a much more dynamic framework than is generally believed, and the characteristic of metal-organic species. The structural rearrangement of the host framework responding to guest molecules proceeds from the “open ” phase to the “close ” phase. MOMMs could also be used as a unique class of materials, with

The local environment of indium atoms in the chalcogenide glass with the stoichiometric composition Ge 28. 33 In6 Se65 67 has been investigated using extended X-ray absorption fine structure (EXAFS) technique. It is found that indium is only coordinated with selenium atoms with a value of three

In this paper an algorithm of the atomic structure visualization is discussed. The atomic structure is presented by a wavelet map. The EXAFS (X-ray absorption fine structure) signal is analyzed by means of the wavelet transform to determine the number of the coordination spheres, the radii

is presented for automated re-refinement of existing structure models in the PDB. A large-scale benchmark with 16 807 PDB entries showed that they can be improved in terms of fit to the deposited experimental X-ray data as well as in terms of geometric quality. The re-refinement protocol uses TLS models

Trimethyltin(IV) complex containing the carboxylate ligand 2,3-methylenedioxybenzoic acid (HL) have been synthesized and characterized in solution state by multinuclear NMR (1H, 13C and 119Sn) using the noncoordinating solvent and also in solid sate by FTIR, mass spectrometry, and X-ray crys

A B S T R A C T: X-ray photoelectron diffraction data for three cleavage surfaces from a crystal of a Norwegian lepidolite containing 2.3 % Rb and 3 % Mn are reported and interpreted. Rubidium is shown to occupy anhydrous interlayer sites equivalent tothose of potassium, and to be distributed

Abstract In this report amorphous, diamondlike, carbon and hydrocarbon films are investigated by two different methods, namely. X-ray scattering and a combi nation of X-ray and neutron reflectivity As specular reflectivity probes the scattering length density profile of a sample perpendicular
