Abstract: Halogenidoligands of niobium cluster compounds A4[Nb6Cl18] (A=K,Na,Rb), which are gained via a solid state chemistry reaction, can be variously substituted in solution. Ligand substitution reactions have been carried out to improve the solubility of niobium cluster compounds in organic solvents. Within this work a total of 30 new niobium cluster compounds have been synthesised. They have been characterised by means of single-crystal X-ray structure analysis and further investigated by IR-, Raman- and UV/Vis-spectroscopic methods.
