(a) Laplacian [∇2ρb(r)] distribution of a representative N—H⋯O hydrogen bond. All the Laplacian maps are drawn at logarithmic intervals in −∇2ρb e Å−5, solid and broken lines represent positive and negative contours, respectively. (b) Laplacian [∇2ρb(r)] distribution of N—H⋯S hydrogen bonds showing the formation of the dimer. (c) Laplacian [∇2ρb(r)] distribution of the C—H⋯O hydrogen bond. (d) Laplacian [∇2ρb(r)] distribution of the C—H⋯S hydrogen bond. |
