报导了[Mn(H2O)4(NCS)2](18-冠-6)单晶的X射线结构分析.它的晶体正交晶系.锰(II)与两个硫氰酸根,四个水分子配合形成顺式八面体的配位分子,并通过其中的水分子与18-冠-6以氢键结合.

关键词: 晶体结构测定, X射线衍射分析, 冠式化合物, 水络合物, 过渡金属络合物, 锰络合物, 硫氰酸根络合物

The title compound is orthorhombic with space group Pnma and a 9.172(1), b 13.457(3), c 19.303(4) ? with d. (calcd.) = 1.42 for Z = 4. The structure was solved by heavy atom method and solved by least squares to R = 0.031. The crown ether does not coordinate directly with the Mn atom. The 4 water mols. and two thiocyanates from a cis distorted octahedral with Mn(II), and coordinate with 18-crown-6 through H-bonds.

Key words: CRYSTAL STRUCTURE DETERMINATION, X-RAY DIFFRACTION ANALYSIS, CROWN ETHER COMPOUNDS, AQUO COMPLEX, TRANSITION METAL COMPLEX, MANGANESE COMPLEX, THIOCYANATO COMPLEX
