Question

Tetragonal crystal system has the following unit cell dimensions

Options

• a = b = c, α = β = γ = 90°

• a = b ≠ c, α = β = γ = 90°

• a ≠ b ≠ c, α = β = γ = 90°

• a = b ≠ c, α = β = γ = 90° γ = 120°

Answer 1

a = b ≠ c, α = β = γ = 90°

Explanation:

For tetragonal a = b ≠ c, α = β = γ = 90°
