(a) Relation between hexagonal (A1, A2) and orthohexagonal (aH, bH) axes and location of the orthohexagonal cell C1. (b) The conventional monoclinic cell [(001) base dashed], the (pseudo)orthohexagonal cell (full lines), and the hexagonal cell (shaded) built overlapping three conventional cells. The scale along c is compressed (modified after Nespolo, Takeda & Ferraris, 1997). |
