 Abstract: The reaction of Bi and Bi2S3 in the Lewis-acidic ionic liquid [BMIm]Cl . 4.3AlCl(3) (BMIm=1-n-butyl-3-methylimidazolium) at 200 degrees C yielded air-sensitive black crystals of (Bi2S2)[AlCl4]. X-ray diffraction on single-crystals revealed a monoclinic structure containing infinite chains infinity 1(Bi2S2) + . These polycations contain bismuth(II,III) and sulfur(-II) atoms, connected by polar covalent Bi-S and Bi-Bi bonds. The assignment of bonds is ambiguous as a distinction between primary and secondary interactions is arbitrary based on interatomic distances. A real-space quantum chemical bonding analysis, including delocalization indices, helped to quantify the interactions and charge distribution, confirming that a simple Lewis formula is inappropriate to describe the polycation.
