Single crystals of AgDy(NO) (tris-ilver didysprosium nona-nitrate) were obtained from a mixture of AgNO and Dy(NO)·5 HO. The new compound crystallizes in space group 432 (No. 213) with = 13.2004 (4) Å, = 2300.2 (2) Å, = 4. The Ag and Dy cations are coordinated by five and six bidentate nitrate anions, respectively. AgDy(NO) is isostructural to several compounds that include alkali metals or ammonium and lanthanide cations, but silver and dysprosium are included for the first time and feature the smallest ion radii observed for this structure type to date. Crystal structures of isotypic compounds are compared.
通过硝酸银(AgNO₃)和硝酸镝(Dy(NO₃)₃·5H₂O)的混合物获得了AgDy(NO₃)₉(三银二镝九硝酸盐)的单晶。这种新化合物结晶于空间群432(编号213),a = 13.2004 (4) Å,V = 2300.2 (2) ų,Z = 4。银(Ag)和镝(Dy)阳离子分别由五个和六个双齿硝酸根阴离子配位。AgDy(NO₃)₉与几种包含碱金属或铵以及镧系阳离子的化合物同构,但银和镝是首次被包含其中,并且具有迄今为止该结构类型中观察到的最小离子半径。对同型化合物的晶体结构进行了比较。
