Figure 2
(a) Ball-and-stick representation of the ZnIm α-phase; the Zn2+ cations are shown as balls and the imidazolate ions as sticks. (b) A close-up of the structure within the blue square displayed in Fig. 2(a). This diagram shows the cooperative bond rearrangement that occurs during the α to β phase transition. The solid blue lines are the links that are broken during the transition, and the blue and white stripped lines show the locations where the imidazolate links are reformed. (c) The ZnIm β-phase. The blue lines show the new positions for the imidazolate links that moved during the transition. (d) Ball-and-stick representation of the ZnIm β-phase. Reprinted with permission from Spencer et al.
