Unlimited number of periodic decagonal tiling (2D-crystal)
The fat and thin rhombus tiles with different acute angles of 36 and 72 degrees can combine to form six different decagonal tiles, of different inner structures, Each decagons composed of ten rhombuses , five thin rhombus and five fat rhombus , where a, b, c, d, e, f, are marked for six different decagons respectively in Figure 1. For the fat rhombus in the decagons of type-a, type-d, type-e and type-f are highlighted in red, purple red, yellow, and light blue, respectively. These six decagons which can be regarded (considered) as basic unit, instead of two types of rhombuses, to fabricate (infinity) tiles in this paper. And be noted that only type-a decagonal tile is five-fold symmetric and the rest decagons are only mirror symmetric.
different unit cells in one periodic decagonal crystals
The five-fold symmetrical tile that can be self-coupled to build up a five-fold tiling,periodic and four-way symmetry tiles (crystals) to infinity
Some smaller unit cells that form different decagonal two-dimensional crystals
Four unit cells that intercepted from a translational decagonal style crystal and form four different crystals.
