Ammonium metatungstate molecular graph according to different crystallization conditions will be variety, Depending on the crystallization conditions, AMT will have several forms of crystals like bellows: (NH₄)₆H₂W₁₂O₄₀.nH₂O or (NH₄)₆H₂W₁₂O₄₀.XH₂O or (NH₄)₆H₂W₁₂O₄₀. Ammonium metatungstate molecular graph is as follows:

Molecular structure, also known as three-dimensional molecular structure, molecular shape, molecular geometry, built based on the spectroscopic data to describe the three-dimensional arrangement of atoms in the molecule. Molecular structure largely affects chemical properties of reactivity, polarity, phase, color, magnetic and biological activity. Molecular structure relates to the position of atoms in space, and the type of chemically bonded relevant, including the dihedral bond lengths, bond angles and dihedral angle among the three adjacent bonds.
