This research aims to make simple modeling of the crystal structure of carbon tetrachloride, diamond, and fullerenes using molymod. The method used is a descriptive quantitative with the research stages including the selection, making, and testing the feasibility of crystal structure. The feasibility of the crystal structure was assessed using a product feasibility test sheet and analyzed using the ideal standard mean equation. The development of a crystal structure model was carried out using a simple and easy method to obtain equipment in the form of molymod. The results of this research indicate that the crystal structure of carbon tetrachloride, diamond, and fullerenes can be interpreted significantly and easily with the help of molymod. The simple model of the crystal structure is also suitable for use as a physics learning medium that can help students understand abstract crystal structure material.
