Figure 7
(a) The H2dazol2+ cation is surrounded by 11 Br− anions. A coordination number (CN) of 11 is generated by the six Br2 anions forming a trigonal prism (tp, thin solid lines) and the five Br1 anions forming a trigonal bipyramid (tbipy, broken lines). The five vertices of the tbipy are placed over the mid-points of the five planes of the tp. (b) The observed distorted and (c) the idealized undistorted D3h model (Edshammar polyhedron).
