Tin occurs in two forms: grey tin and white tin. The properties of grey tin and white tin are listed below. Grey tin: boiling point $2543\,\text{K}$, no electrical conductivity in solid or liquid, brittle. White tin: boiling point $2533\,\text{K}$, good electrical conductivity in solid and liquid, malleable. Which structural change could occur as grey tin is converted into white tin?
