WebMar 12, 2024 · 2. There are two kind of symmetries in your molecule: the symmetries of the equilateral triangle (the dihedral group of order 6 = the symmetric group S 3) and the … In crystallography, the hexagonal crystal family is one of the six crystal families, which includes two crystal systems (hexagonal and trigonal) and two lattice systems (hexagonal and rhombohedral). While commonly confused, the trigonal crystal system and the rhombohedral lattice system are not equivalent (see section crystal systems below). In particular, there are crystals that have trigonal symmetry but belong to the hexagonal lattice (such as α-quartz). http://pd.chem.ucl.ac.uk/pdnn/symm2/laue1.htm he louvain en hainaut
