Polymorf - Knowhwere- BCC and CP elements

Body centered cubic (BCC) structure elements

Ba, Cr, Cs, Eu, a-Fe, K, Li, Mo, Na, Nb, Ra, Rb, Ta, V, W

Crystal lattice/polyhedral framework

The BCC crystal lattice and polyhedral framework can both be modeled as two

interpenetrating expanded CP lattices as shown previously.
