A hexagonal prism.
A hexagon is a 2-dimensional shape. A "structure" implies a 3-dimensional shape but you have not specified whether it is a hexagonal pyramid, a hexagonal prism or some other shape that is [partly] based on a hexagon. Without that information it is not possible to give a more helpful answer.
Hexagonal Prism
cylinder
A hexagonal prism has 8 faces: 2 hexagonal bases and 6 rectangular lateral faces. The rectangular faces are perpendicular to the hexagonal bases. Therefore, there are 6 perpendicular faces in a hexagonal prism.
The net of a 2 dimensional shape can be folded into a 3 dimensional shape
hexagonal prism
The given net shows a hexagonal prism, which is a three-dimensional shape with two hexagonal faces and six rectangular faces connecting them. The hexagonal faces are the bases of the prism, while the rectangular faces are the lateral faces. When the net is folded along the edges and assembled, it forms a hexagonal prism with a regular hexagon as its base and top.

Hexagonal Prism

There are several polyhedra with 8 vertices. Some examples are: A heptagonal pyramid A hexagonal prism A hexagonal dipyramid (two hexagonal pyramid stuck together along their hexagonal bases) There is also the 2-dimensional polygon - the octagon.
A hexagonal prism has 2 hexagonal bases (which are faces) and 6 lateral rectanglur faces.

Octagon. * * * * * An octagon is 2-dimensional. The regular 3-d shape (all faces the same) is the octahedron, but a hexagonal prism also has 8 faces.
