Abstract
Tungsten tetraiodide WI4 (1) is produced by a high-temperature reaction of WTe2 and I2 in a vacuum sealed ampoule. The crystals of 1 belong to the triclinic crystal symmetry, space group P -1, Z = 4, a = = 7.9291(3) Å, b = 10.7695(4) Å, c = 10.8117(4) Å, a = 85.668(1)°, b = 71.772(1)°, g = 71.559(1)°, V = = 831.60(5) Å3, d calc = 5.523 g/cm3. The structure of 1 consists of tetrameric W4I16 molecules in which W atoms are in a distorted octahedral environment formed by I atoms.
