$\mathrm{[CpMoCl_2]_2}$ obeys the 18 electron rule. The correct structure of this compound is (atomic number of Mo = 42)
(a)
(b)
(c)
(d)
Answer
Answer: C ✓ checked by 4AB · confidence high
Explanation
With four bridging chlorides each Mo counts 6 (Mo) + 5 (Cp) + 6 (4 × 1.5 e from μ-Cl) + 1 (Mo–Mo) = 18 electrons; only structure (c) satisfies the rule.
