crystalline

adj. made of crystal, crystal-like, opaque

CRYSTAL is a quantum chemistry ab initio program, designed primarily for calculations on crystals (3 dimensions), slabs (2 dimensions) and polymers (1 dimension) using translational symmetry, but it can be used for single molecules. It is written by V.R. Saunders, R. Dovesi, C. Roetti, R. Orlando, C.M. Zicovich-Wilson, N.M. Harrison, K. Doll, B. Civalleri, I.J. Bush, Ph. D’Arco, and M. Llunell from Theoretical Chemistry Group at the University of Torino and the Computational Materials Science Group at the Daresbury Laboratory near Warrington in Cheshire, England. The current version is CRYSTAL06. Earlier versions were CRYSTAL92, CRYSTAL95, CRYSTAL98 and CRYSTAL03.

In chemistry and mineralogy, a crystal is a solid in which the constituent atoms, molecules, or ions are packed in a regularly ordered, repeating pattern extending in all three spatial dimensions.The word crystal originates from the Greek word "Krystallos" meaning clear ice, as it was thought to be an especially solid form of water. The word once referred particularly to quartz, or "rock crystal". Most metals encountered in everyday life are  polycrystals. Crystals are often symmetrically intergrown to form crystal twins.'''
