N2 - A mixture of two structurally different cluster phases I and II with the general chemical formula W5Br12·BiBr3 is obtained as a product of the WBr6 reduction reaction with elemental bismuth at 280 °C. The elemental composition of the mixture is determined by the energy-dispersive X-ray spectroscopy and inductively coupled plasma atomic emission spectrometry. For the single crystals selected from a mixture of phases I and II their crystal structures are determined, and the powder X-ray diffraction analysis is performed for the polycrystalline mixture. In the crystal structure of I, square-pyramidal cluster fragments are bridged by bromine atoms into infinite chains by the W–Bra–a–W interaction. In the structure of II, BiBr3 (W–{BraBiBrBra}–W) molecules incorporate into the chain instead of the bridging bromine atom.
