The solvothermal reaction among tellurium, manganese, and the Zintl compound K4Ge9 has led to the formation of a polymeric mixed-valent complex {[Mn(en)(3)](2)(Ge5Te10)}(n), (1; en=ethylenediamine). The most interesting structural feature of this material is the presence of three different oxidation states of germanium centers and the formation of Ge-Ge bonds in the infinite polymeric chains (1/infinity){[Ge5Te10](4-)}. X-ray photoelectron spectroscopy characterization confirms the different oxidation states of germanium.
