Question

The coordination geometry around the manganese in decacarbonyldimanganese(0) is

• A. Octahedral
• B. Trigonal bipyramidal
• C. Square pyramidal
• D. Square planar

Answer 1

The Correct Option is A

Solution: Decacarbonyldimanganese(0), represented as Mn(CO)₁₀, is a complex where manganese is surrounded by ten carbon monoxide ligands.

Coordination Number: In this complex, manganese exhibits a coordination number of 10, which typically leads to an octahedral geometry.

The carbon monoxide ligands are arranged around the manganese atom in a way that minimizes repulsion between the ligands, resulting in an octahedral shape.

Geometry: The octahedral arrangement is characteristic of complexes with a higher coordination number, where the ligands occupy the vertices of an octahedron around the central metal atom.

Thus, the coordination geometry around manganese in Mn(CO)₁₀ is: Octahedral
