All the crystal molecular structures of c1, c2, c4 and c5 belong to monoclinic system
and only one molecular unit were observed, although these compounds have different types and positions of substituents in the phenoxymethyl unit.
hornblende, muscovite (monoclinic) and plagioclase (triclinic),   and  directions do not correspond to the pole of the respective crystallographic plane (100) (010) (001), except for  in the monoclinic system
It crystallizes in the monoclinic system
and is isostructural with herderite.
In the monoclinic system, the cell is based on the shortest possible vectors in the ac plane with b the unique axis.
In all cases then, the practice for the monoclinic system would be to select a conventional cell based on the shortest vectors in the ac plane (b-axis unique) for primitive as well as centered cells.
It was crystallized in a monoclinic system
with a space group P21/n.
80[degrees]; dispersion r < v, significant; nonpleochroic; orientation is given as X (or Y) ^ a = -11[degrees], Z = c, but this is not possible in the monoclinic system
Carbon tetrachloride III crystallizes in the monoclinic system
The compound crystallizes in the monoclinic system
, space group P2(1)/c with a = 7.
In addition, to facilitate the use of these conventions, Volume A of the International Tables for Crystallography has been expanded to give explicitly the required space group settings in the monoclinic system
Ferrisurite crystallizes in the monoclinic system
and has pseudo-orthorhombic symmetry ([beta] [approximate] 90[degrees]).
Skipping over the technical discussions of the isometric, tetragonal and monoclinic systems
, I headed straight to the "Catalogue of American Localities of Minerals," where Dana listed many of our Bay State communities and the geologic treasures they hold.
