Abstract
Single crystals of Ag3Dy2(NO3)9 (tris-ilver didysprosium nona-nitrate) were obtained from a mixture of AgNO3 and Dy(NO3)3·5 H2O. The new compound crystallizes in space group P4132 (No. 213) with a = 13.2004 (4) Å, V = 2300.2 (2) Å3, Z = 4. The Ag and Dy cations are coordinated by five and six bidentate nitrate anions, respectively. Ag3Dy2(NO3)9 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.
