The organic groups can control and modify the structure of inorganic framework, for its rigidity in conjunct mode, flexibility in stereochemistry and strong capability of coordination.
Organic chemistry is so abstract and full of a large number of knowledge that the beginners may find it hard to master, especially the stereochemistry.
