Complexes between the heavier lanthanoid nitrates Ln(NO~3~)~3~ and 15βcrownβ5 (**1**) and 18βcrownβ6 (**2**) ethers were isolated and characterized. Both 1:1 and 4:3 complexes are formed with each Ln(III) ion, except in the case of Gd and **2**. The thermal transformation of the 1:1 complexes into t
## Abstract Complexes of lanthanoid trinitrates Ln(NO~3~)~3~ with 15βcrownβ5 ether **1** (Ln = La, Ce, Pr, Nd, Sm, Eu, Gd) and with 18βcrownβ6 ether **2** (Ln = La, Ce, Pr, Nd) having a 1:1 stoichiometry as well as 4:3 complexes with **2** (Ln = La, Ce, Pr, Nd, Sm, Eu, Gd) have been synthesized and
