The emerald green solid, OsOF5, m. p. 59·2, b. p. 100·6°, is the major product of the fluorination of osmium dioxide. Vapour pressure–temperature relationships for the compound are: 32–59°(solid), log Pmm=–2266//T+ 9·064; 59–105°(liquid), log Pmm=–1911//T+ 7·994. The solid is dimorphic being orthorhombic below the transition point of 32·5° and body centred cubic, a= 6·14 Å, above it. It is paramagnetic
翡翠绿色固体,OsOF 5,熔点59·2,沸点100·6°,是二氧化fluor氟化的主要产物。该化合物的蒸气压与温度的关系为:32–59°(固体),log P mm =–2266 // T+ 9·064; 59–105°(液体),对数P mm =–1911 // T+ 7·994。固体在转变点低于32·5°时为正交晶体,其上方为a = 6·14Å,为体心立方。它是顺磁性和磁化率服从居里-外斯定律约,与θ = + 6°时,与温度无关的磁矩的存在,μ = 1·47 BM OSOF的红外光谱5(气体)是类似的复查的5(气体),并且与C 4 v分子对称性一致。
