Synthesis and Crystal Structure Determination of a Dimeric Complex of Dimethylammoniumbis(<i>p-tert</i>-butylcatecholato) borate

“…7 The role of non-metal cations differs from metal cations, since they generally do not coordinate to oxygen in the same way, and may act instead as hydrogen bond donors to the structural unit. Continuation persistently our progressing work on borates, [8][9][10][11] the process of the self-assembly of organic and inorganic moieties has been performed under DMF solution conditions, and yielded original borate with organic amine, namely dimethyl ammonium bis(p-tertbutylcatecholato) borate.…”

“…N-H hydrogen bond ( Table 3). The B-O distances range from 1.472(15) to 1.495(13)Å, and the mean distance for the B-O bonds is 1.479 Å, with the O-B-O angles ranging from 104.4 (10) to 113.3(10) ( Table 2). The bond distances and angles are similar to those reported previously in related borate compounds.…”

Crystal Structure of Tertiarybutyl Ammonium Bis[(naphthalene-2,3-diolato)borate] Dimethyl Sulfoxide Solvate

“…6 The role of non-metal cations differs from metal cations due to the fact that they generally do not coordinate to oxygen in the same way, and may act instead as hydrogen-bond donors to the structural unit. As part of our progressing work on spiroborates, [7][8][9] the process of the selfassembly of organic and inorganic moieties has been performed under mild and aqueous solution conditions, and obtained original borate with organic amine associated with the solvent molecule, namely tertiarybutyl ammonium bis[(naphthalene-2,3diolato)borate] dimethyl sulfoxide (Fig. 1).…”
