What … Pincer complexes are formed by the binding of a chemical structure to a metal atom with at least one carbon-metal bond. The structure of CH 4, with four hydrogen atoms arranged around a central carbon atom as shown in Figure \(\PageIndex{3}\), is tetrahedral: the hydrogen atoms are positioned at every other vertex of a cube. Certain crystalline compounds may be treated as chemical compounds despite varying in composition according to the presence or otherwise of elements trapped within the crystal structure. As be seen from the chemical structure, the compounds isolated from the aerial part of the Isatis tinctorial are mainly alkaloids, flavonoids, and phenolic compounds.
