THE BEADED MOLECULES
串珠分子模型的美妙世界

Bead models can be viewed as a kind of valence sphere models (or tangent sphere models 價球模型或是切球模型), in which beads represent electron pairs....

I just learned a kind of molecule called twistane the other day. It looks so interesting and I decided to make a bead model for it.

Prismane with 3-, 4-, and 5-fold rotational symmetry:

The structure of a penta-prismane is similar to that of a cubane. Instead of 4-fold rotational symmetry, one has a five-fold rotational symm...

The tetrahedrane derivative with four tert-butyl substituents, tetra-t-butyl tetrahedrane, was synthesized by the Austrian chemist,Günther M...

According to the wiki: A pagoda （塔） is the general term in the English language for a tiered tower with multiple eaves common in Nepal, I...

I made a bead valence sphere model of adamantane (chemical formula C 10 H 16 ), which is a cycloalkane and also the simplest diamondoid.

Neopentane, also called dimethylpropane, is a double-branched-chain alkane with five carbon atoms. (from wiki)

I made a bead valence sphere model of cyclohexane, C 6 H 12 , which seems to reproduce all important structural features of this molecule. ...

Fullerane is any hydrogenated fullerene or fully saturated fullerene. For instance, the fully saturated C 60 is C 60 H 60 . One can make a ...

I should forget another platonic alkane, the tetrahedrane. The shape of this molecule based on the valence sphere model is just like 10 sph...

In principle, we can make the valence sphere model for any molecule with beads. But in practice, it is a little bit hard to thread the Nylo...

I just made a bead VSM (valence sphere model) of cubane (C 8 H 8 ) by myself. The structure looks neat to me. Every valence electron pair ...

There is no doubt that tetravalent molecules such as methane occupy an important place in the chemical bond theory. In 1865, German chemist...

Using beads, one can make a faithful representation of the so-called valence sphere model (VSM) or tangent sphere model for a molecule propo...

Qian-Rui and I discussed the possibility of using beads to build molecular models for compounds that contain hybridizations other than sp 2 ...
