Facile synthesis of novel lithium β-diketonate glyme adducts: the effect of molecular engineering on the thermal properties

Abstract

Coordination of monoglyme and diglyme to Li ion, in addition to the anionic hexafluoro-acetylacetone, gives rise, respectively, to a polymeric network and dimeric units with challenging mass transport properties.

Sodium β-Diketonate Glyme Adducts as Precursors for Fluoride Phases: Synthesis, Characterization and Functional Validation

“…Concluding, the present syntheses of adducts 2 , 3 , and 4 give us a good understanding of the polyether chain’s effect on the central metal β-diketonate structure’s coordination chemistry. Analogous coordination behavior has recently been observed for the Li and K ions using the hfa anionic ligand and the same glyme Lewis base ligands [ 43 , 44 ].…”

A One‐Pot Synthesis of “K(hfa) glyme” Adducts: Effect of the Polyether Length on the Ion Coordination Sphere

“…[21][22][23] Former studies have shown that glymes play a crucial role in stabilizing complexes of alkaline-earth, [24][25][26][27][28] transition [29,30] and rare-earth metals [31,32] through oxygen-ion complexation. Recently, we have also devoted our attention to alkali metals, namely Li [33] and Na. [34] We have recently reported the synthesis and the crystal structures of Lithium β-diketonate complexes with a polymeric, [Li 12 [33] In regard to Na, a novel monomeric complex of the type, Na(hfa) * tetraglyme, [34] has been synthesized and applied to the sol-gel processes of NaYF 4 phase.…”

Highly stable CsPbBr3 perovskite phases from new lead β-diketonate glyme adducts

“…[57][58][59][60][61] Lead β-diketonates are used as precursors in vapor phase processes, such as the case of Pb(tmhd) 2 [(H-tmhd = 2,2,6,6-tetramethyl-3,5-heptanedione)], Pb(acac) 2 , [(H-acac = 2,4-pentanedione)], and their derivatives. 56,62 It has been demonstrated that glymes, through oxygen-ion complexation, are very important for the stabilization of alkaline, 61,63,64 alkaline-earth 65,66 and rare-earth 67 metals. The presence of such a class of multidentate ligands, in fact, permits also to fine-tune the properties of the final metal adducts in terms of thermal stability, moisture-and air-sensitivity, solubility, and volatility.…”
