RDG isosurfaces (0.4 a.u) between adjacent molecules (dimer 2 and dimer 3) related to π⋯π stacking interactions between substituted phenyl rings in the Bic crystal structure. Symmetry operations used are (a) −x, 1 − y, 1 − z. and (b) 1 − x, 1/2 + y, 3/2 − z. The colour scale represents the value of sign(λ2)ρ.
