Molecular formula : MW : CAS :
nature : an intermediate crystalline communities. Characteristics of symmetric elements of the triple axis of symmetry. It can be divided into six-party of rhombohedral crystal lattice body. The former cell parameters : a = b c � α = β = 90 °, γ = 120 °. The latter cell parameters : a = b = c, α = β = γ <120 °, 90 ° �
