Synthese und Kristallstruktur des Lewis‐Säure/Base‐Addukts AlCl 3 ·C 3 N 3 Cl 3

Synthesis and Crystal Structure of the Lewis Acid‐Base Adduct AlCl 3 ·C 3 N 3 Cl 3 The reaction between cyanuric chloride (C 3 N 3 Cl 3 ) and the strong Lewis acid AlCl 3 yielded colorless crystals of the adduct AlCl 3 ·C 3 N 3 Cl 3 . The crystal structure was determined by single crystal X‐ray diffraction at room temperature and was solved in the space group $P{\bar1}$ 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) Å 3 . In the crystal structure, AlCl 3 is closely associated to the triazine ring with Al–N distances of 2.042(3) Å and 2.067(4) Å, respectively. The AlCl 3 ·C 3 N 3 Cl 3 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.
