Are there any pure substances whose liquid density is greater than their solid density, other than water?

As the title suggests, the solid density of water is lower than that of its liquid state, which is why ice floats on top of water. I searched online to find out what would happen if ice had a higher density than water One answer is that Jack and Rose will get married. . . . . . Are there any other pure substances whose liquid density is greater than their solid density? I conducted a few small experiments and checked several parameters, and found that solids have a higher density than liquids.
At present, it seems that if the adjective \"pure\" is used, only water meets this condition；
So the question is, why is the density of solid pure water lower than that of its liquid form? ? ?
It is caused by a special crystal structure. This information is not helpful in finding substances with a lower density than liquids. I also don’t know what the purpose of finding this substance is
For now, among substances of the same kind, water seems to be the only one whose solid density is less than that of its liquid state
There are some materials with high melting points; they contain no water and have a high degree of purity. They are transported in barrels, in liquid form during filling, but become solid at room temperature. It won’t cause the tank to expand even if it crystallizes.
