A packing nHanR with n odd will therefore necessarily belong to the trigonal
system and can have either a hexagonal or a rhombohedral lattice (Verma &
Krishna, 1966). Other symmetries that can arise by restricting the arbitrariness of
the ...

Introduction to Crystallography
If the lattice is rhombohedral, it is still possible to choose a cell with hexagonal
dimensions, but the cell will have 3 times the volume of the primitive cell. The
relationship of the primitive rhombohedral cell to the triply primitive "hexagonal"
cell is ...

Crystal Structure Determination
For this reason, many texts recognize only six crystal systems, and treat trigonal
as a subset of hexagonaL The trigonal system does, however, have one unique
feature, and that is the rhombohedral unit celL In this case, the smallest primitive
...
