Question
![Metal complexes can be assigned systematic names based on their chemical formulas.
For example, the name of neutral metal complexes and cations follow this pattern:
tetraaquadichlorochromium 1I1) [Cr(H,0)4Cl,]*
The names of complex anions follow this pattern:
diaquatetrachlorochromate(II) [Cr(H,0),CL]
In each case the name of the complex consists of a root that gives the metal, its oxidation state, and whether or not the entire complex is an anion or not. The
root is preceded by one or more prefixes that give the number and chemical identity of the ligands.
Here are some additional rules you need to keep in mind.
• If a complex has more than one type of ligand, prefixes are written in alphabetical order ignoring number syllables, e.g. "tetraaqua" is written before
"dichloro" because the "a" in "aqua" is earlier in the alphabet than the "c" in "chloro".
• There are a number of widely-accepted abbreviations for the chemical formula of common complex ligands which you should learn. The following complex
ligands may be used in this problem:
formula
name
abbreviated formula
(CH), (NH),
ethylenediamine
en
CH,NH,CO,
glycinato
gly
ethylenediaminetetraacetate
EDTA
• When the name of a ligand already contains a syllable indicating number (such as the di- in ethylenediamine), construct the prefix by using a Greek
number syllable and enclosing the name of the ligand in parentheses.
number
Greek syllable
2
bis
3
tris
4
tetrakis
For example, the name of [Co(en); is tris(ethylenediamine)cobalt(III).
Note: When just one ligand is used the name is still enclosed in parentheses.
Using these rules, you can write the names of the ocomplexes given in this problem.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fda31eafe-0785-44e5-9bff-b3b897be6388%2Ff67c4a8f-a88b-4771-b254-af0686c5ca39%2Fe80jilg_processed.png&w=3840&q=75)
