摘要: Abstract The reaction between tetra(2-pyridyl)pyrazine (tppz) and molecular bromine afforded [ ( H 4 tppz + ) Br - 2 ] , characterised by means of FT-Raman spectroscopy single-crystal X-ray diffraction. crystal structure showed that the final framework can be considered as being made up self-assembly building blocks (Br−, Br2, H4tppz4+), driven exclusively non-covalent interactions. nature positions peaks for linear symmetric ion were interpreted based on MP2/LanL2DZ calculations.
