Inorganic crystal structures

Abstract

Part 1: cubic-close-packed arrays (usually of anions) projected along the diagonal of an octahedron - a four-fold axis hexagonal-close-packed arrays (usually of anions) projected along the three-fold axis normal to the close-packed layers hexagonal-close-packed arrays projected along an axis parallel to a CP plane but normal to a CP row in that plane hexagonal-close-packed arrays projected along a CP row of atoms. Part 2: projection along the shortest axis of the FCC projection along the shortest axis of mixed (H+C) stackings primitive cubic arrays and derived structures primitive hexagonal arrays and some derived and related structures the stereochemistry of Valence and lone pair electrons topological transformations noncommensurate Vernier or Nonius structures structures that can be related to BCC or PC packing alloy structures with edge-capped tetrahedra, octahedra, square antiprisms, stellae quadrangulae and/or tetraedersterns silicate structures.
