To answer the question about coordination numbers in coordination compounds, follow these steps:
1. Understand the Coordination Number: Coordination number refers to the number of ligand donor atoms bonded to the central metal atom/ion.
Here's a detailed solution, step-by-step, for each compound provided:
1. [tex]\[ K_{m} ICed , I \][/tex]
- Coordination number: This entry seems unclear and may not represent a standard coordination compound.
2. [tex]\[ He _{8,3} F \][/tex]
- Coordination number: This entry does not seem to follow standard coordination compound notation and is ambiguous.
3. [tex]\[ \left( N_4 CN_3\right)^2 \][/tex]
- Coordination number: This entry is incomplete and its coordination number cannot be determined from the given text.
4. [tex]\[ \left[ Tu \left( CN_4 \right]^2 \right. \][/tex]
- Coordination number: This entry appears to be incomplete or possibly a typographical error. It is difficult to determine the coordination number from the given text.
5. [tex]\[ \left[ NaNOH_2, P^{2+} \right. \][/tex]
- Coordination number: This entry seems erroneous or incorrectly formatted and as it stands, is not a commonly recognized coordination compound format, making it challenging to determine the coordination number.
6. [tex]\[ M_4 CNO_2 F \][/tex]
- Coordination number: This also seems ambiguous and not clear in the context of coordination compounds.
Given the confusing and potentially incorrect formatting of the compounds listed, it’s difficult to classify each according to their coordination numbers confidently. Generally, the proper notation for coordination compounds, such as [tex]\(\left[Fe(CN)_6\right]^{4-}\)[/tex], would allow easier interpretation of coordination numbers.
Now to solve the oxidation state for the central metal atom in [tex]\(\left[ HeI_2 \right]^{-}\)[/tex]:
To determine the oxidation state of He in [tex]\(\left[ HeI_2 \right]^{-}\)[/tex]:
- Generally, Helium (He) is a noble gas and does not form compounds in typical scenarios. This might again be a typographical error, as helium is inert and usually does not form bonds in this manner.
Given the ambiguity in the problem setup and the unusual listings, it might be best to review the source material for clarity or correct any potential typographical errors to provide accurate solutions.
If you aim to practice determining coordination numbers and oxidation states in coordination chemistry, consider using examples with clear and conventional notation.
