Figure 2.
Arrangement of one-dimensional linear chains in crystal formed by 2 (stereoviews). Three CH3 groups containing tBupy are omitted for clarity. (a) One-dimensional linear chains link along the a axis and pile along the b axis. Hbim−1, red; Ni2+, green; and tBupy, blue. (b) A perspective stereoview of linear chains, as viewed along the a axis.
