inorganic chemistry - When are the prefixes bis, tris etc. used in ...
Both the prefixes bis-, tris-, tetrakis-etc. and the prefixes di-, tri-, tetra-etc. are used to describe how many times a certain single ligand attaches to a central metal — and this usage is no different here than in typical molecule nomenclature.
using bis, tris, tetrakis - CHEMISTRY COMMUNITY
2015年11月19日 · Postby Anne Cam 3A » Fri Nov 27, 2015 11:08 pm. You would use bis-, tris-, and tetrakis- when the ligand already has prefixes like di- and tri- in its name, or if you know for sure it is polydentate (includes bidentate, tridentate, hexadentate or generally anything over monodentate). If you were naming 2 dien ligands, you would write bis (dien ...
When do we use the prefixes bis, tris, tetrakis, etc? - CHEMISTRY …
2019年12月8日 · When a ligand is polydentate and you have more than one of these ligands, you use bis-, tris-, etc. This is done because some polydentate ligands already have the prefixes di-, tri-, etc. in them (ex: di ethylene tri amine). By using bis-, tris-, and the alternate prefixes, you can clearly show how many polydentate ligands there are and avoid ...
Di, Tri, Tetra vs. Bis, Tris, Tetrakis - CHEMISTRY COMMUNITY
2017年11月28日 · so you would use di, tri, tetra on ligands that don't have said prefixes in their names already, eg dichlorido. while if you were to write (dien)2, instead of it being didiethlynetriamine which would be confusing, it's bisdiethylenetriamine, same with (en)2 for example, it would be bisethylenediamine, just because it's less confusing.

Di-, Tri-, Tetra- vs Bis-, Tris-, Tetrakis- - CHEMISTRY COMMUNITY
2019年11月25日 · The prefixes bis-, tris-, and tetrakis- are used when a ligand already has a Greek prefix. It's either that or you use it when the ligand is polydentate. Top. Tiffany_Chen 2K. Posts: 106. Joined: Fri Aug 30, 2019 7:15 am.

2021年11月23日 · Re: bis-, tris, tetrakis, prefixes Post by Emily Engelkemier 1E » Tue Nov 23, 2021 2:54 am You use the bis-, tris-, tetrakis- prefixes when the ligand's name already starts with di-, tri-, or tetra-, of if it is polydentate.
Bis, Tris, Tetrakis, Pentakis - CHEMISTRY COMMUNITY
2019年12月2日 · Postby Ryan Yee 1J » Tue Dec 03, 2019 2:21 am. You use Bis, Tris, Tetrakis, and Pentakis when the ligand itself has a prefix on it. These new prefixes will help denote how much of a ligand you have whereas the ones already on the ligand denote how much of an element you have within a ligand. This is to help avoid redundancy when naming.
Naming of [Pt (py)4] [PtCl4] - Chemistry Stack Exchange
2020年5月23日 · Again py is neutral ligand whereas Cl is anionic (-1). So, [Pt(py)X4]X2+ [P t (p y) X 4] X 2 + is positively charged and [PtClX4]X2− [P t C l X 4] X 2 − is negatively charged. In IUPAC nomenclature, for a coordination complex, the name of cation is written first and of anion at end (cation or anion may be simple or any coordination entity).
Bis, Tris, Tetrakis - CHEMISTRY COMMUNITY
2020年12月12日 · Re: Bis, Tris, Tetrakis. Postby Javier Perez M 1H » Wed Dec 16, 2020 2:56 am. bis, tris, etc is generally used to name molecules or atoms with more than one bond. It seems the mono-, di- prefixes (which indicates how many atoms or molecules are present) is canceled out when dealing with these complex bonds. Top.
When to use bis, tris, etc. - CHEMISTRY COMMUNITY
2021年12月4日 · You would use the prefixes bis-, tris-, tetrakis-, etc. when there are multiple polydentate ligands. For example, diethylenetriamine, shown as (dien), is a tridentate ligand so you would name it bisdiethylenetriamine when there's two of them, it would shown as (dien)2. You wouldn't use the prefix if there's only one (dien) ligand. Top. Mia Orr 3B.
