The structure was studied by X–ray diffraction (XRD).
Nano and micro structures of diatomite are consist of silica, and many in shape ancillary to structure of diatom [1].
The structure of pumice is heterogeneous near circular pore structure and a vesicular structure with prolongation of air bubbles during the magma solidification [8].
The main mineral component of diatomite was cristobalite low (SiO2), which showedthe tetragonal structure and correspondswith the JCPDS File Card No. 01–076–0940 (Fig. 1(d)) [13].

In addition, fluorinated compounds are considerably interested in modem agrochemistry and medicinal chemistry because of their enhanced activities and decreased toxicities [6].
Crystal Data and Structure Determination.
The structure was solved by direct methods with SHELXS-97 [8] and expanded using Fourier difference techniques.
It is clear that all the spectroscopic data for compound 2 are in accordance to its structure.
The molecular structure of compound 2 is shown in Fig. 1.

Many different structures have been postulated as new reddish pigments, such as related perovskites containing Al, Cr, Y and/or other rare earths [32-35] or Cr-doped CaYAlO4 (K2NiF4 structure type) [36] and Y2Sn2O7 (pyrochlore) [37] solid solutions.
