The hexahydrate is a metal aquo complex consisting of octahedral [Co(H 2 O) 6] 2+ ions associated with sulfate anions (see image in table). [3] The monoclinic heptahydrate has also been characterized by X-ray crystallography. It also features [Co(H 2 O) 6] 2+ octahedra as well as one water of crystallization. [2]
The names "caffeine" and "3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione" both signify the same chemical compound. The systematic name encodes the structure and composition of the caffeine molecule in some detail, and provides an unambiguous reference to this compound, whereas the name "caffeine" simply names it.
Although most compounds are referred to by their IUPAC systematic names ... [Ti x Zr 1−x]O 3 (e.g., x = 0.52 is lead zirconium titanate) Plumbane – PbH 4; Li
3 COOH, which is commonly called acetic acid and is also its recommended IUPAC name, but its formal, systematic IUPAC name is ethanoic acid. The IUPAC's rules for naming organic and inorganic compounds are contained in two publications, known as the Blue Book [ 1 ] [ 2 ] and the Red Book , [ 3 ] respectively.
