What is claimed is: 1. A chemical compound represented by the following general having formula (IV): wherein, in the formula, R 2 and R 3 independently represent hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or a halogen atom; R 4 and R 5 independently represent an alkyl group having 1 to 6 carbon atoms, or an aryl group having 1 to 6 carbon atoms; R 6 and R 7 independently represent hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or a halogen atom; R 13 represents a protective group of phenolic hydroxy group; and X represents germanium atom, or tin atom, or a salt thereof. 2. The compound according to claim 1 , wherein each of R 6 and R 7 represents a halogen atom. 3. The compound according to claim 2 , wherein each of R 2 and R 3 represents a hydrogen atom. 4. The compound according to claim 1 , wherein each of R 2 , R 3 , R 6 and R 7 represents a hydrogen atom. 5. A chemical compound having formula (IV): wherein, in the formula, R 2 and R 3 independently represent hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or a halogen atom; R 4 and R 5 independently represent an alkyl group having 1 to 6 carbon atoms, or an aryl group having 1 to 6 carbon atoms; R 6 and R 7 independently represent hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or a halogen atom; R 13 represents a protective group of phenolic hydroxy group; wherein at least one of R 2 , R 3 , R 6 and R 7 represents an alkyl group having 1 to 6 carbon atoms, or a halogen atom; and X represents silicon atom, germanium atom, or tin atom, or a salt thereof. 6. The compound according to claim 5 , wherein each of R 6 and R 7 represents a halogen atom. 7. The compound according to claim 6 , wherein each of R 2 and R 3 represents a hydrogen atom. 8. A chemical compound having formula (IV): wherein, in the formula, R 2 and R 3 independently represent hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or a halogen atom; each of R 4 and R 5 represents an ethyl group; R 6 and R 7 independently represent hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or a halogen atom; R 13 represents a protective group of phenolic hydroxy group; and X represents silicon atom, germanium atom, or tin atom, or a salt thereof. 9. The compound according to claim 8 , wherein each of R 6 and R 7 represents a halogen atom. 10. The compound according to claim 9 , wherein each of R 2 and R 3 represents a hydrogen atom. 11. The compound according to claim 8 , wherein each of R 2 , R 3 , R 6 and R 7 represents a hydrogen atom.
