Synthesis and Crystal Structure of Tris(2-amino-indolinium)-hexachlorobismuthate(III) monohydrate

摘要

The salt tris(2-amino-indolinium)hexachlorobismuthate(III) monohydrate [C₈H₉N₂]₃BiCl₆·H₂O crystallizes at room temperature in the monoclinic system with space group P2₁/n. The unit-cell dimensions are: a = 15.1853(14), b = 11.7761(9), c = 17.3168(13)Å, β = 103.937(8)° with Z = 4. The crystal structure of this salt was solved by Patterson methods and refined by full-matrix least squares on F2 to final values of R = 0.0293 and wR = 0.0786. The structure consists of monomeric BiCl₆3- anions, monoprotonated 2-amino-indolinium cations and water molecules. These entities are interconnected by means of hydrogen bonding contacts [N-H…O(Cl) and O(W)-H…Cl], forming a three-dimensional network.
