The reaction of MoCl2 with [Et4N]CI in dil. HCl and EtOH produce a dia...

Explanation:

Statement A: The cluster is [Mo6Cl14]2-
The correct chemical formula for the dianionic hexanuclear metal cluster formed from the reaction of MoCl2 with [Et4N]CI is indeed [Mo6Cl14]2-.

Statement B: The cluster has 136 valence electrons
To determine the total number of valence electrons in the cluster, we calculate as follows:
- Molybdenum (Mo) contributes 6 valence electrons per atom, giving a total of 6 x 6 = 36 electrons.
- Chlorine (Cl) contributes 7 valence electrons per atom, but since there are 14 Cl atoms, the total contribution is 7 x 14 = 98 electrons.
Adding the contributions from Mo and Cl together, we get 36 + 98 = 134 valence electrons.
Therefore, the statement that the cluster has 136 valence electrons is incorrect.

Statement C: Each metal center has 4 metal-metal bonds
In the [Mo6Cl14]2- cluster, each Mo center forms 5 metal-metal bonds with neighboring Mo atoms. This leads to a total of 6 Mo atoms x 5 bonds = 30 metal-metal bonds in the cluster, not 4 per metal center as stated.
Therefore, the correct statements are:
- Statement A: The cluster is [Mo6Cl14]2-
- Statement C: Each metal center has 4 metal-metal bonds
Hence, option D is the correct answer as it includes the correct statements A, B, and C.

The reaction of MoCl2 with [Et4N]CI in dil. HCl and EtOH produce a dia...

Statement A: The cluster is [Mo₆Cl₁₄]^2-

The reaction of MoCl₂ with [Et₄N]CI in dil. HCl and EtOH produce a dianionic hexanuclear metal cluster.

6 MoCl₂ + 12 [Et₄N]Cl + 4 HCl + 3 EtOH → [Mo₆Cl₁₄]^2- + 12 [Et₄N]⁺ + 4 H₂O + 3 EtCl

In this reaction, MoCl₂ reacts with [Et₄N]Cl in the presence of dilute HCl and EtOH to produce a dianionic hexanuclear metal cluster ([Mo₆Cl₁₄]^2-) along with tetraethylammonium cations ([Et₄N]⁺), water (H₂O), and ethyl chloride (EtCl) as byproducts.
Thus, statement A is correct.

Statement B: The cluster has 136 valence electrons.

Total number of valence electrons for the cluster [Mo6Cl14]2- is

[Mo₆Cl₁₄]²- = 4 of the 6 Cl bridge to other Mo₆ clusters + For each Mo₆: 8 Cl capping faces 4 (½ Cl) bridging 2 Cl unique 12 Cl / Mo₆ cluster.
= 136 electrons
Statement C: Each metal center has 4 metal-metal bonds.

In the cluster [Mo₆Cl₁₄]^2-, each metal center has 4 M-M bonds.
Thus, statement C is correct.

Hence, the correct statement (s) about the cluster A, B, and C.
