WebA molecular lattice is characterized by the presence of stable and closely-packed molecules. They are located in the nodes of the crystal lattice. They are held by the Van der Walsh forces that are ten times weaker than the … WebA crystalis made up of one or more atoms, called the basisor motif, at each lattice point. The basismay consist of atoms, molecules, or polymerstrings of solid matter, and the lattice provides the locations of the basis. Two Bravais lattices are often considered equivalent if they have isomorphic symmetry groups.
