...built after working them out mathematically. One typical globular molecule looked like a crocheted doily cut up and sewed together in a three-dimensional geometrical object. This she described as a "polyhexagonal lacelike pattern of atoms with the characteristic lacunae or holes, the whole forming a truncated tetrahedron, a cage-like space enclosing a structure roughly resembling a six-point diamond." Molecules in this weight class were called "space-enclosing cyclols." Significance of this work is that the way a molecule is built is bound up with its chemical behavior...
