The Zintl phase K 4 SnTe 4 reacts with tetraphenylphosphonium bromide in methanol to give the polytelluride (Ph 4 P) 2 Te 4 · 2 CH 3 OH. The compound crystallizes in the monoclinic space group C2/c with lattice constants a = 2329.6(11) pm, b = 1472.0(6) pm, and c = 1461.9(6) pm with ß = 111.34(3)°. Significant structural units are tetratelluride(2−) anions with CH 3 OH molecules hydrogen bonded to both ends of the anion.
