Bead model of the longest EMAC

Qian-Rui made this bead model of the longest EMAC (Extended Metal Atom Chain) for Prof. J. McGrady (Univ. of Oxford) who is an expert on the electronic structures of this class of molecules and is going to visit our department today. In making this model, Qian-Rui chose 10mm beads for both metal-metal and metal-ligand bonds, and 8mm beads for chemical bonds of surrounding ligands. The pitch of the surrounding ligands is slightly larger than the true molecular structure of this molecule. Only a single nylon cord with about 7 meter long is used for this model.

Here is a photo for the giant structure of this molecule hung in the main lobby of our department.
