Authors:Mark Niemeyer
Abstract:
Synthesis of Dimethoxyethane and Tetrahydrofuran Complexes of Rare‐Earth Nitrates – Solid State Structure of Pr(NO3)3(thf)4 The solvated rare‐earth nitrates Ln(NO3)3(thf)n (Ln = Pr, n = 4 ( 1 ); Ln = Ho ( 2 ), Yb ( 3 ), n = 3 and Ln(NO3)3(dme)2; Ln = Pr ( 4 ), Ho ( 5 )) were obtained from Ln(NO3)3(H2O)x and HC(OCH3)3. Pale green thermally labile crystals of 1 were characterized by X‐ray crystallography. The praseodymium atoms in two independent monomeric molecules show capped trigonal prismatic and pentagonal bipyramidal coordination, respectively.
Keywords:Coordination chemistry  Crystal structure  Lanthanides  Nitrates  Praseodymium
