title: Tris[(R)-lactamide-kappa2O,O']zinc(II) tetrabromozincate.
abstract: 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.
