What liquids can be found in the void space? Is there any material natural or otherwise a free floating liquid that can exist in space?

No liquid can be completely stable in a vacuum, since all liquids have some non-zero vapour pressure, and so will evaporate at some rate. However some liquids have an exceptionally low vapour pressure, and so can be used in a vacuum.

The vapour pressure of silcone fluid DC705, which is used in diffusion pumps is 2.6e-8, and it is designed to function in a high vacuum.

If a location could be found at which it was warmed sufficiently to remain liquid (in deep space it would just freeze, whereas too close to the sun and its vapour pressure would rise) it could remain in a liquid state for some time.  Not indefinitely but it could be stable for a while.
