Easily constructed paper stereomodels
Brian H. Freeland, R. J. O'Brien · Journal of Chemical Education · 1971
A system of low cost paper stereomodels for personal use by students of organic chemistry has been outlined in this journal. The student of coordination chemistry has a similar need for the dimensional models of the standard "solid" geometrical figures. These authors extend on previous described models of tetrahedron by a simple construction from a sealed empty envelope.
