摘要

zýkaite样品是在Krušné霍利山脉(捷克共和国)米库洛夫附近的废弃Lehnschafter矿中发现的。它呈不规则的白色到淡绿色的圆形到球形聚集体，大小可达1.5厘米，由微小的针状晶体组成，长度可达5 - 10 μm。其经验公式为(Fe3.79Al0.02)Σ3.81[(AsO4)2.66(PO4)0.20(SiO4)0.07]Σ2.93 (SO4)1.07(OH)0.44·15H2O(3点分析平均值;基于As+P+S+Si = 4 apfu)。Zýkaite可能是单斜的，其单位胞参数由x射线粉末衍射数据修正:a 21.195(8)， b 7.052(2)， c 36.518(17) Å， β 91.07(2)°和V 5458(2) Å3。拉曼光谱记录了(SO4) 3-和(SO4)2-在zýkaite晶体结构中的存在。与水分子和(AsO4)3-基团的振动相连接的多个拉曼带表明，在zýkaite的晶体结构中存在更多结构上不等效的这些基团。

Zýkait z dolu Lehnschafter u Mikulova v Krušných horách (Česká republika) - popis a Ramanova spektroskopie

The zýkaite samples were found at abandoned Lehnschafter mine near Mikulov in the Krušné hory Mts. (Czech Republic). It occurs as irregular white to light greenish rounded to spherical aggregates up to 1.5 cm in size composed of tiny acicular crystals up to 5 - 10 μm in length. Its empirical formula can be expressed as (Fe3.79Al0.02)Σ3.81[(AsO4)2.66(PO4)0.20(SiO4)0.07]Σ2.93 (SO4)1.07(OH)0.44·15H2O (mean of 3 spot analyzes; on the basis of As+P+S+Si = 4 apfu).Zýkaite is probably monoclinic, with the unit-cell parameters refined from X-ray powder diffraction data: a 21.195(8), b 7.052(2), c 36.518(17) Å, β 91.07(2)° and V 5458(2) Å3. Raman spectroscopy documented the presence of both (AsO4)3- and (SO4)2- units in the crystal structure of zýkaite. Multiple Raman bands connected with vibrations of water molecules and (AsO4)3- groups indicate the presence of more structurally non-equivalent these groups in the crystal stucture of zýkaite.
