Question

Give the systematic name of this copper compound. Use bis- instead of di- when denoting ethylenediamine.(Cu(en)2(H2O)2)I2*All of the numbers are subscripts there are no exponents or coefficients.

Answer 1

The systematic name of the complex is:
`[Cu(en)_2(H_2O)_2]I_2`

diaquabisethylenediaminecopper(II) iodide

Step-by-step explanation:

`[Cu(en)_2(H_2O)_2]I_2` = Given complex whose naming is to be done:

Rules for naming of the coordination compounds :

• The name of ligand should be written first and then metal.
• The charge of metal indicated with the Roman numerals and enclosed in the parenthesis after metal name.
• The ligand's names written should be in an alphabetical order before the metal ion.
• Ligands that include a numerical prefix in the name use the prefixes bis or dia for 2, tris for 3, or tetrakis for 4 to indicate their number.
• If the complex ion is an anion, we drop the ending of the metal name and add –ate.

The cationic part of the complex: diaquabisethylenediamine copper(II)

The anionic part of the complex: iodide

The systematic name of the complex is:
`[Cu(en)_2(H_2O)_2]I_2`

diaquabisethylenediaminecopper(II) iodide
