Synthesis and X-ray characterization of the organotriboroxinate salts [Me3NCH2CH2OH][Ph4B3O3] and [NEt3H][Ph3B3O3(OH)], and the X-ray structure of the triarylboroxine, (4-MeOC6H4)(3)B3O3
The synthesis and characterization of the organotriboroxinate salts [Me3NCH2CH2OH][B3O4Ph4] (1) and [NEt3H][B3O3Ph3(OH)] (3) are reported. Compound 3 contains the first example of a hybrid inorganic/organic triboroxinate anion. Compounds I and 3 have been structurally characterized by single-crystal X-ray diffraction studies, which reveal H-bond ion-pair interactions between anions and cations in both 1 and 3, and additional anion-anion H-bond interactions in 3. Compound 3 exists as a dimer in the solid-state. A single crystal X-ray diffraction study of the triarylboroxine, (4-MeOC6H4)(3)B3O3, is also reported
