K(H_2O)_6Al(H_2O)_6(SO_4)_2和K(C_4H_5O_6)(C_4H_5O_6=D,L-酒石酸)的结构:钾离子和氧原子之间成键研究(英文)
Investigation of bonding between Potassium Ion and Oxygen Atom:Structures of(H_2O)_6Al(H_2O)_6(SO_4)_2 and K(C_4H_5O_6)(C_4H_5O_6=D,L-Tartaric Acid)
摘要
利用水合硫酸铝在氢氧化钾存在的条件下在水中发生共晶作用得到无色块状的配合物K(H2O)6Al(H2O)6(SO4)2晶体,其中钾离子(K+)形成KO6八面体的配位几何构型。将D,L-酒石酸和相同当量的KOH反应生成配合物K(C4H5O6)(C4H5O6=D,L-酒石酸),其中K+以KO8多面体的形式被8个氧原子围绕形成一个扭曲的立方体形式。
Co-crystallization of hydrated aluminum sulfate Al2（SO4）3 in the presence of potassium hydroxide in water gave colorless block crystals of complex K（H2O）6Al（H2O）6（SO4）2 in which the K^＋ is octahedral coordination geometry with the NO6 octahedron. Treatment of D,L-tartaric acid with equal equivalent of KOH resulted in formation of K（C4H5O6） （C4H5O6=D,L-tartaric acid） in which the K^＋ ion is surrounded with the KO8 polyhedra in a distorted cubic fashion by eight oxygen atoms.
