Solide Molydbenum(II) Chloride Cluster compounds From a Hudrogen Bonding Poin of View
2005 (English)Doctoral thesis, comprehensive summary (Other academic)
This thesis is based on a study of solid Molybdenum(II) chloride cluster compounds. The emphasis of the text is on the hydrogen network in the different compounds. The main analysis tool has been single crystal x-ray diffraction, and in some cases theoretical calculations have been performed to confirm the hydrogen positions.
It has been shown that the Mo(II) cluster is a very good promoter for hydrogen bonds. The hydrogen bond networks studied here are fairly rigid and strong, except for one compound where the easy loss of a water molecule changes the water structure dramatically.
There are several ways to alter the crystal structure and of course alter the hydrogen bond network.
Ø Change the syntheses with respect to pH
Ø Change the apical halogenides
Ø Introducing cations instead of H3O+
Ø Using protonated organic amino bases as cations and different organic solvents
All of these methods have been tested and evaluated. The general conclusion is that the cluster units are nicely ordered in the hydrogen bond network.
