Structures and thermal analyses of Werner clathrates and coordination polymers

Includes bibliographical references.The crystal structures of several organometallic host complexes and their inclusion compounds with small, polar, organic guests have been elucidated. These compounds form a diverse range of structure types, from hydrogen bonded networks of Werner-type inclusion compounds to one- and two- dimensional coordination polymers. Depending on the packing arrangement of the host molecules in the clathrate, the guest molecules (G) may become trapped in cages, stacked in one-dimensional channels or sandwiched between layers of host molecules. Examples of all three clathrate types can be found in the different inclusion compounds presented here.

Examples of all three clathrate types can be found in the different inclusion compounds presented here. The crystal structures of twelve Werner clathrates and four coordination polymers were solved using single crystal x-ray diffraction techniques. In addition, all compounds were characterised by thermal analysis techniques, including differential scanning calorimetry, thermogravimetry and hot-stage microscopy
