The concept of effective (non-integer) coordination number is useful to describe distorted structures. Structures of silicates are governed by silica chains accommodating to large cations.doi:10.1007/978-94-007-4771-5_5Batsanov, Stepan S.
Knowledge of the crystal structures of both anhydrous and hydrated compounds is briefly reviewed, and the problem of relating crystallographic and chemical results is discussed. One approach lies in the study of oriented transformations, i.e., reactions in which the structure of a crystalline ...
Crystalline materials enable essential technologies, and their properties are determined by their structures. Crystal structure prediction can thus play a central part in the design of new functional materials1,2. Researchers have developed efficient heu

Crystal Structure (redirected fromCrystal structures) Medical The arrangement of atoms, ions, or molecules in a crystal. Crystals are solids having, in all three dimensions of space, a regular repeating internal unit of structure. Crystals have been studied using x-rays, which excite signals from...
Polytypism occupies a singular position in the structural crystallography uniting features of polymorphism and diversity of crystal structure built of definite units. In the structural systematics the polytype structures are considered in relation to fragmentary, interstratified, hybrid (both commensurate and...

The FPSQ model was used to obtain the fitting curves of the FTIR spectra and derive the intrinsic properties of the material that were found to be in agreement with the measured data. The structure-property relationships were successfully established based on the Raman mode results. The optimal ...
