ABSTRACT:
A color coded molecular model assembly kit is provided for representing organic molecular structures and shapes comprising two basic and complementary construction units capable of being interlocked. The first basic construction units are color coded plastic tubes of three different lengths such that when coupled to two of said second basic construction units the distances between the centers of the coupling means represent 1.36 Angstroms, 1.54 Angstroms and 1.81 Angstroms respectively and represent the bonds between adjacent atoms. The second basic construction units are color coded coupling means for said tubes according to the valency of the atoms to be joined, the center of said coupling means representing atom conters, said coupling means having radial arms substantially located on the surface of a sphere with the center of the coupling unit being the center of the sphere. Said coupling units are made of plastic and are of two types, one type adapted for planar-trigonal coupling of three said tubes separated by angles of about 120.degree. and the other type adapted for tetrahedral coupling of four said tubes separated by angles of about 109.degree.. Said first and second construction units are capable of being joined together and held immobile by friction by having said radial arms and/or the cavities of said tubes tapered so that skeletal models of complex organic macromolecules may be assembled such that the distance between the centers of two directly connected coupling means represents the distance between joined atoms.
