Lattice system The 14 Bravais lattices are grouped into seven lattice systems: triclinic, monoclinic, orthorhombic, tetragonal, rhombohedral, hexagonal, and cubic . WebIn a face-centered cubic crystal, each atom has 12 nearest neighbors (NN). That’s the theoretical maximum number of NNs possible–each of those NNs contributes a bond, giving the crystal structure very high stability. FCC has 6 next-nearest neighbors, and 24 next-next nearest neighbors. Face-Centered Cubic Lattice Constants
