Synthesis, Structure and Hirshfeld Surface Analysis of Phosphine–Imidazolium Salt

In the field of homogeneous catalysis, particularly in anti-Markovnikov hydration, sterically demanding phosphine ligand has found to be very effective. Here we report the crystal structure of a phosphine-imidazolium salt which crystallized in monoclinic space group P21/c with a = 16.6623(13) (A), b = 10.6686(8) (A) and c = 12.8916(11) with = 110.232(2). Hirshfeld surface analysis show that the halogen–hydrogen interaction leads to a formation of 1D chain.
