rhomboedrycznym
Rhomboedrycznym is the genitive singular masculine or neuter form of the adjective rhomboedryczny, which in Polish means "rhombohedral." A rhombohedron is a three-dimensional figure, a special case of a parallelepiped where all six faces are congruent rhombuses. It is also known as a trigonal trapezohedron. A cube is a perfect example of a rhombohedron where the rhombuses are squares. The angles between adjacent faces are not necessarily 90 degrees, unlike in a cube. The unit cell of certain crystal systems, such as the trigonal crystal system, is a rhombohedron. In crystallography, the shape and arrangement of atoms within a crystal lattice determine its macroscopic form, and some minerals exhibit rhombohedral symmetry. The term rhomboedrycznym would be used in a sentence describing a property or characteristic related to such a shape, for example, "właściwości rhomboedrycznym" (rhombohedral properties) or "sieć rhomboedrycznym" (rhombohedral lattice).
