None:
A pure open-framework germanate material is obtained using an organic structure directing agent (OSDA) prepared by a photochemically induced[2 + 2] cycloaddition reaction. The structure of this new material, named ITQ-35, is determined by combining precession electron diffraction tomography (PEDT) and powder X-ray diffraction (PXRD) methods. This material presents tridirectional 8-ring pores connected by 12-ring channels, with one of the lowest framework densities reported until now for a pure germania zeolitic material (12.7 T/1000 Å3), and similar to that of the aluminogermanate PKU-9.

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
