Figure 10
Electrostatic potential on the Hirshfeld surface of the metformin cation. The chloride atoms interacting with the metformin cation are shown. (a) Generated by the cation. (b) Generated by neighboring molecules in contact with the metformin cation. Contributing molecules: chloride (x, y, z) and 17 MetCl molecules around the central cation (list given in Table S6). The N3 atom with Lp is in front of the molecule. The closest interacting chloride anions are represented as green spheres and their symmetry number is given: (i) x, y, z; (ii) $[-x, y+ {1\over 2}, -z+{1\over 2}]$ ; (iii) $[x, - y+{1\over 2}, z+{1\over 2}]$ ; (iv) $[ -x+1, y+{1\over 2}, -z+{1\over 2}]$ ; (v) -x+1, -y+1, -z+1; (vi) $[x+1, -y+, z+{1\over 2}]$ .
