Abstract
In the centrosymmetric dimeric title compound, [Pr2(C5H9O2)2(C11H19O2)4(CH3OH)2], the two praseodymium(III) atoms are eight-coordinate and are bridged by O atoms from the two pivalate anions. Each PrIII ion is further coordinated by two chelating 2,2,6,6-tetramethyl-3,5-heptanedionate (thd−) ligands and one methanol molecule. The distance between the two PrIII ions is 4.273 (5) Å. Intramolecular hydrogen bonds exists between the methanol hydroxy group on one PrIII atom and a chelating O atom of a thd− ligand coordinated to the symmetry-related PrIII atom.
