# Theoretical Calculation of Lattice Parameter from Space Group

If I am given a compound which belongs to, say the cubic $\text{Ia}\bar 3\text{d}$ space group, is there a known way to calculate the lattice parameter of the compound? In general, can lattice parameters be calculate from knowing what space group the compound belongs to?

• On the other hand, lattice parameters and crystal system can be known independent of space group and atoms by indexing a diffraction pattern. – wismuthaft Nov 15 '15 at 10:52
