Synthesis and crystal structure determination of Br2SeIBr polyhalogen�?�chalcogen

[摘要] In this paper polyhalogenâ€�?�chalcogen Br₂SeIBr was synthesized and the crystal structure was determined by single crystal X-ray diffraction method. This compound was prepared in the temperature range 150â€�??50°C which was brownish-red in colour and crystallized in monoclinic crystal system and space group ð‘�?2_1/c with four molecules per unit cell. Lattice parameters were: ð‘�? = 6.3711(1), ð‘�? = 6.7522(2), ð‘�? = 16.8850(5) Ã�?, ð›�? = ð›�? = 90°,ð›�? = 95·96°, 𝜈 = 722·45 Ã�?³.
