Coordination polymers are infinite network solids made up of metals and ligands. They can be either discrete or 1-3 D and can have interesting and tuneable magnetic and themal expansion properties. 

Transition metal complexes are interesting as bio-inorganic model systems [155-157] and also because of their material properties (conductivity, magnetism, porosity) and as potential hosts for a variety of guests [156-161]. Whereas salt-like 2D-Cun-coordination polymers are well documented [158-162], far less is known about their neutral counterparts. 

Semiconductor and metallic nanoparticles have been extensively studied as active components in wide variety of basic research and technological applications due to their new or improved optical, electric, and magnetic properties compared to their bulk counterparts [1]. Therefore, exploitation of well-known materials in their new nanosized forms is strongly motivated area of research. Prussian Blue [2], an old pigment, is a coordination polymer formed by reaction of either hexacyanoferrate(II) anions with ferric (Fe(III)) cations, or hexacyanoferrate(III) anions with ferrous (Fe(II)) cations [3], According to X-... 

In most fluorides with organic nitrogen bases, these are protonated and enter the stmcture as counter cations. However, the example of 4,4 -bipyMnF3 (bipy = bipyridine) shows that it is also possible to consfruct hybrid coordination polymers with the amine and fluoride as bridging ligands (Figure 40). The stmcture is modulated at low temperature and has ID magnetic properties ...
