You're asking for the melting point of a molecule with the formula C6H12. This formula alone doesn't tell us the exact melting point because it represents multiple different molecules, all with the same number of carbon and hydrogen atoms but different arrangements. These are called isomers.

Here are some examples:

* Hexane: A straight-chain alkane with a melting point of -95.3 °C.

* Cyclohexane: A cyclic alkane with a melting point of 6.5 °C.

* Methylcyclopentane: A cycloalkane with a methyl group attached, with a melting point of -142 °C.

To determine the melting point, you need to specify the specific structure of the C6H12 molecule you're interested in.
