As listed in Table 3215, substances with large bonding energies usually have high melting temperatures.

Table 3215. Bonding energies and melting temperatures of hydrogen bonding-type substances.

Bonding type

Substance
Bonding energy
Melting point (°C)
kJ/mol kcal/mol eV/Atom, Ion, or Molecule
Hydrogen
Typical value 10-40      
NH3 35 8.4 0.36 -78
H2O 51 12.2 0.52 0

Note that page3239 describes the correlation between the bonding energies and melting temperatures of different substances.
