摘要
Yellow crystals of the phosphorus selena bromide alpha-P4Se3Br2, [monoclinic, C2/c, Z = 8 a = 12.724(3) angstrom, b = 14.732(3) angstrom, c = 12.553(3) angstrom, beta = 116.60(3)degrees] were obtained front the reaction of P4Se3 and bromine at 80 degrees C in sealed glass ampoules. The crystal structure features discrete molecules of the formula alpha-P4Se3Br2 according to the well-known alpha-form of P(4)Ch(3)I(2) molecules (Ch = S, Se).
