摘要
湖南瑶岗仙钨铝矿发现于1948年,但一直未作正式报道。最近笔者用里特弗尔德法对其进行了晶体结构的修正。瑶岗仙钨铅矿的a=b=0.544503(3)nm;c=1.20495(1)nm;α=β=γ=90°。经笔者对瑶岗仙钨铅矿晶体结构修正得到的氧原子坐标为:X=0.2637,Y=0.1137,Z=0.0706;W-O的键长为0.17826nm,O-W-O键角为123°和103°。
Although stolzite of Yaogangxian, Hunan Province, China, was discovered in 1948, no formal report concerned with this mineral has been published. Recently its crystal structure has been refined by means of the Rietveld method. The cell dimensions of this mineral are: a =b - 0.544503(3)nm; c = 1.20495(1)nm; α = β = γ = 90°. The X, Y and Z coordinates of the atom O which were refined by the authors are 0.2637, 0.1137, 0.0706, respectively. The length of the W-O bond is 0.17826nm, and the bond angles of O-W-O are 123° and 103°, respectively.
