Basically, common technique for synthesizing CaCu3Mn4O12 includes wet chemistry and solid state method.
Good microstructure was obtained in the CaCu3Mn4O12 sintered at 700 °C in atmospheric condition; which the main microstructure features are uniform in grain size with a low porosity and also promotes more compact arrangement of grain structure compared to 600 °C.

; Crystal structure; Electrical conductivity Abstract New molecular conductors on the base of 8,8'-dibromo cobalt bis(dicarbollide) anion, (BEDT-TTF)2[8,8'-Br2-3,3'-Co(1,2-C2B9H10)2] (1), and (BEDT-TTF)[8,8'-Br2-3,3'-Co(1,2-C2B9H10)2] (2) were synthesized and their crystal structures and electrical conductivities were determined.
Introduction The permanently growing research activities in the field of molecular metals, provoked by the discovery of the first molecular superconductor more than 25 years ago [1], have led to a solid basic knowledge on the chemistry, structure, and principal physical properties of organic charge-transfer salts [2,3].
The crystallographic data and structure refinement parameters are given in Table 1.
A fragment of crystal structure of (BEDT-TTF)2[8,8'-Br2-3,3'-Co(1,2-C2B9H10)2] (1) In general, the BEDT-TTF radical cations in the structure of 1 are packed some more tightly than in the structure of 3 [6] that, probably, can be explained by difference in the anion size.
The structure of the [8,8'-Br2-3,3'-Co(1,2-C2B9H10)2]- anion has not been described before.

All The above mentioned properties should make such materials ideal candidates for extensive applications, for example, for the promising host matrixes of host-guest chemistry.
Then the physicochemical properties of the guest molecules could be tailored through orientation and/or conformation inside the hierarchically porous structure [16].
The HOPC has a large effect on the exothermal property of CL-20 due to its superior hierarchically ordered space structure, thus it is a useful platform to clarify the roles of ordered porous structures in the host-guest energetic composites.
Therefore, the synthesized HOPC materials exhibit superior hierarchical porosities, which can provide a fast mass transport and diffusion pathways for guest molecules in host-guest chemistry.

A dumbbell-liked organ-metal composite was prepared with wet chemistry.
Theoretically, quasi one-dimensional structures should be observed, and it was the case in the third configuration.
At one time, one-dimensional structures have been found increasing significance both in theory and in application [4-5].
But until now, little relative works have been reported partly due to the complexity of composition and structure.
With the development of nanotechnology, more complex substantial structures and higher resolution keep increasing demand.
