Hexatomic

Hexatomic is a term used in chemistry to describe substances that possess a certain arrangement of atoms. Specifically, it refers to molecules or compounds that consist of six identical or very similar atomic centers. This arrangement is also known as an octahedral geometry, where the six atomic centers are connected to a central atom or a central group of atoms in a symmetrical and three-dimensional manner.

In inorganic chemistry, hexatomic compounds often involve transition metals as the central atom, surrounded by six ligands. These ligands can be negatively charged ions, neutral molecules, or even a combination of both. The arrangement of the ligands around the central atom is determined by the coordination geometry of the compound, which can be influenced by various factors such as the size, charge, and geometry of the ligands.

The term hexatomic is often used interchangeably with terms such as octahedral complex and octahedral geometry. However, the term hexatomic specifically emphasizes the arrangement of six identical or very similar atomic centers, rather than the overall geometry of the compound. Hexatomic compounds are found in various fields of application, including catalysis, materials science, and medicine.

Some examples of hexatomic compounds include platinum(II) complexes, such as cisplatin, which are used as anticancer agents in chemotherapy. Other examples include hexagonal dipyramidal compounds like the borohydrides, which are used as reducing agents in various chemical reactions.

Overall, the term hexatomic is a useful descriptor for substances that exhibit a unique arrangement of six atomic centers, with applications in various fields of chemistry and beyond.
