a compound melts if the molecules get fully mobile with the network structure the molecules need more of energy to overcome the attracion energy andget mobile therefore it has high melting point

I do not know if you mean crystalline? if that is the answer well, it is strong due to the fact that atoms are fully packed with each others in a repetitive pattern. The central atoms generally have a hybridization of sp3 and tetrahedral structures (with 4 perfect covalent bonds). Therefore, materials like crystalline ceramics exhibit strong structures, but that makes them easily breakable too!!

If the molecules are locked together forming a tight structure, then you need to add heat in order to make them more mobile.
