Summary of symmetry in any chemical compound

This article can be summarized in quite simple words. In this article there is proper information about the symmetry. There are two types of symmetry in any chemical compound. These are centrosymmetric and noncentrosymmetric. Sometime for diffraction the data it is very difficult to select between centrosymmetric and noncentrosymmetric. This is because both are quite different terms. The best way is that to use centrosymmetric description. This description is easy to use and there is very low risk of result disorder.

It is recommended that the ideal option is that use centrosymmetric even the results are not same as required. If disordered results happened so its means in that case the crystal is composed of two or more structure or molecules and these are unable to be differentiated. On the other side if the model is tested from noncentrosymmetric space group so it means that it will lead to poor results and through this space group a new structure will be found. The most important problem in the analysis of crystal structure is that differentiate between the two spaced group and these are centrosymmetric and noncentrosymmetric and these group may occurred in the form of different pairs. From the crystal analysis if the structure is near to centrosymmetric so its diffraction data is quite insensitive. Then after this in this article there is demonstration about some examples.

 In all three examples the author described there examples and in this article he has described in detail the centrosymmetric structure in noncentrosymmetric space group. The first example is about Dichloro. The structure of this compound is described in detail. It can be seen that the main structure of this crystal after analysis is asymmetry with you make its bond with other compound. Then after this that structure has been defined in space group. This crystal structure is defined in proper way in this example with complete numerical analysis. Then BFMP model of this structure has been described in detail. Then after this the next crystal component has been described in this article are 10-tetrathiacyclododecane. This crystal compound is used by many authors.

This crystal structure has been described in the form of diffraction data and also there is also not a single reason to describe this structure in the form of centrosymmetric Pbcm. There is proper numerical data of this compound in described in detail.  There is proper table for the chemicals that are present in this compound. In this table there is information about the x, y and z components are described in the form of table. Then after this the structure of that compound is explained in space group. It can be seen that there is extremely small difference from every dimension. The last component that has been tested in this article is 4-dithintetracarboxylic N,N – dimethyldiimide and acridine. The complete information about this compound has been described in numerical form. Afterwards in the last part of this article there is discussion about all three examples.

 These three examples are almost as the same according to information. Then it is concluded that it is quite necessary to describe the crystal structure in centrosymmetric form. It can be seen that from the first two examples the disorder in the chemical compounds comes in the form of different molecules. In the last example it can be seen that disorder comes in the form of random interchange of different molecules. There is very low tangible advantage when you are using centrosymmetric method. In this representation there is complete knowledge about the part that contributing the complete structure of crystal molecules. Then in the last there are some comments about this discussion and this article is ended after the computational details of these three examples.
