Synthesis, crystal structure and Hirshfeld surface analysis of a polymeric bismuthate(III) halide complex, (C6H6N3)2[BiCl5]·2H2O

Abstract

The synthesis and the crystal structure of a new halide-bridged polymer, namelycatena-poly[bis(1,2,3-benzotriazolium) [[tetrachloridobismuth(III)]-μ-chlorido] dihydrate], {(C6H6N3)2[BiCl5]·2H2O}nare reported. The structure comprises polyanionic zigzag chains of formula [(BiCl5)2−]nrunning along thec-axis direction. The 1,2,3-benzotriazolium cations are linked between these polymer chains,viathe water molecules, giving rise to left- and right-handed helical chains. Hirshfeld surface analysis and fingerprint plots were used to decode the intermolecular interactions in the crystal network and determine the contribution of the component units for the construction of the three-dimensional architecture.
