been obtained by reaction of cesium carbonate and corresponding beta-diketone. The molar
ratio of reagents and the presence of water molecules have an influence on the final prod-
ucts. Cesium salts containing hydrated beta-diketones, Cs(CF3C(OH)2CH2C(OH)2CF3)
(CF3COO) and Cs(CF3C(OH)2CH2COCH3)(tfac), were formed at 50% ligand molar excess
of hexafluoroacetylacetone and trifluoroacetylacetone, respectively. Pure Cs(hfac) and
Cs(tfac) can be obtained using stoichiometric molar amounts of reagents. For Hptac
and Hbtfac, no hydration of ligands occurred; nevertheless, water molecules formed
Cs(OH2)(ptac) and Cs(OH2)(btfac), respectively.
Single crystal XRD analysis shows that crystal packing of Cs(hfac) and
Cs(CF3C(OH)2CH2COCH3)(tfac) can be represented by pseudo chain motifs, while the
structures of other salts form pseudo-layered ones. The links of chains (layers) are con-
nected through Cs…F and Cs…O interactions; oxygens of water in Cs(OH2)(ptac) and Cs
(OH2)(btfac) also interact with cesium.
All the cesium beta-diketonates investigated decompose during heating in the
temperature range 25–600 °C according to TG data. Destruction of Cs(OH2)(ptac) and
Cs(OH2)(btfac) begins with loss of water.
The results presented at this paper can be used as a basis for synthesis of more compli-
cated cesium-containing compounds.
