Synthese und Kristallstruktur des Lewis‐Säure/Base‐Addukts AlCl3·C3N3Cl3

Synthesis and Crystal Structure of the Lewis Acid‐Base Adduct AlCl₃·C₃N₃Cl₃ The reaction between cyanuric chloride (C₃N₃Cl₃) and the strong Lewis acid AlCl₃ yielded colorless crystals of the adduct AlCl₃·C₃N₃Cl₃. The crystal structure was determined by single crystal X‐ray diffraction at room temperature and was solved in the space group with Z = 4, a = 7.3802(7) Å, b = 9.688(1) Å, c = 16.272(2) Å, α = 72.80(1)°, β = 89.97(1)°, γ = 87.23(1)°, and V = 1110.0(2) ų. In the crystal structure, AlCl₃ is closely associated to the triazine ring with Al–N distances of 2.042(3) Å and 2.067(4) Å, respectively. The AlCl₃·C₃N₃Cl₃ units are connected with each other via intermolecular N···Cl donor–acceptor interactions, forming tape‐like arrangements in the ac‐plane, with tapes running parallel to the a‐axis.
