“…For these reasons, amide± metal complexes have attracted much interest. Following our work on metal±amide crystalline complexes (Bekaert et al, 2002a(Bekaert et al, ,b, 2003, we now report a new zinc complex, (I), with 2-hydroxypropanamide (lactamide).…”

The title compound, tris[(R)-2-hydroxypropanamide-kappa2O,O']zinc(II) tetrabromozincate, [Zn(C3H7NO2)3][ZnBr4], contains one monomeric six-coordinate zinc complex cation and one tetrahedral [ZnBr4]2- anion. Both Zn(II) atoms lie on threefold axes. Coordination in the cation occurs via the amide and hydroxy O atoms [Zn-O = 2.074 (5) and 2.073 (6) A] and has a distorted octahedral geometry, with cis-O-Zn-O angles in the range 76.2 (2)-109.2 (2) degrees . In the crystal structure, the cations and anions are linked by N-H...Br and O-H...O hydrogen bonds, generating a three-dimensional network.

“…Following our work on metal-amide crystalline complexes (Bekaert et al, 2002a(Bekaert et al, ,b, 2003, we recently reported a new zinc complex with 2-hydroxypropanamide (lactamide), a bidentate ligand (Bekaert et al, 2005). In the [Zn(lactamide) 3 ] 2+ cation, the Zn atom, coordinated in a bidentate fashion via amide and oxide atoms O of each ligand, presents similar Zn-O bond lengths [2.074 (6) Å ].…”

“…The synthesis of cationic and anionic boron species is of considerable interest from the viewpoint of fundamental curiosity and their potential usefulness as ligands and catalysts. The chemistry of anionic boron species has been developing since the first isolation of a lithioborane , whereas the investigation on cationic boron species has synthesized boron dications ([L 3 BR] 2+ ) and trications ([L 4 B] 3+ ) . Most of the isolated boron dications and trications are stabilized by Lewis bases that are directly bonded to the electron‐deficient boron centers.…”
