Part III - Spin Crossover in Coordination Polymer Networks

Chapter 10

Building up a Complex 3D Iron Network

> This is a view down the c-axis, in which initially only the five inequivalent iron atoms have been included. As the film progresses, the three different chains arranged in two different layers perpendicular to the a-axis can be seen including the iron atoms linked through pyrimidine ligands.

> The silver atoms are arranged in such a way that they form layers in between the iron atom layers making an oversized club sandwich! Adding the C and N atoms from the cyanide groups in the anions, the very complex 3D network that connects all the irons can be seen.

Chapter 11

Cell Doubling

> This is the h0l zone taken above and below the phase transition. The appearance of extra spots can clearly be seen. These additional spots appear between the others reflecting the pseudo-B-centering of the super cell.
