Keywords: Coordination polymers; layer; p-p stacking.
The structure was characterized by elemental analysis and IR spectroscopy.
Thus, 1D chains extended into a 2D planar layers structure (Fig. 2b).
These 2D thick layer structures are further extended into 3D structures through hydrogen bonding interaction and p-p aromatic stacking interactions.

Therefore just the kinetic energy of fluid gases and potential energy induced by structure-fluid particles are concerned.
Then the energy is simply consisted by the kinetic energy Ek of the gas molecules and potential energy Ep coming from structure-fluid particles interaction.
The usage of the term force field here is scalar potential differing from the usage in chemistry and computational biology.
The specific decomposition of the terms depends on the molecular structure of both fluid and solid.
With regard to the coupling interaction between the solid structure and fluid, the physical model is built on basis of following opinions.

Abstract.
And they have been generally used as precursors for chemical vapor deposition (CVD), metal-organic chemical vapor deposition (MOCVD), laser materials, electrochemical devices, organometallic liquid crystal, proton NMR shift reagents, the petroleum industry, and analytical chemistry [1-6].
So many authors have also reported the synthesis, luminescence, spectroscopic characteristics, structure, and others properties of b-diketonate complexes [7-9].
In previous literature, the thermo-chemistry and the kinetics of the b-diketone complexes have been reported [10,11].
Some data were quite different between the ligand and the complex, which showed the structure change of the ligand after coordination.

Samples showed changes in the overall structure and defect chemistry with an increase in calcination temperature.
The XRD patterns revealed 3 major phases, these were CeO2 (fluorite cubic structure), Iron oxide (Fe2O3) hematite structure, and Iridium oxide structure.
The Lattice fringes for the samples calcined at 800 °C predominantly exposes the (111) planes of CeO2 fluorite structure and (200) planes of FeSmO2 structure for 900 °C and the (420) planes of CeO2 structure for 1000 °C calcined samples.
