(a)—molecular structure of 1. Selected bond lengths (Å) and angles (deg): d(Co1-N1) = 2.014(4), d(Co1-N2) = 2.016(4), d(Co1-Cl1) = 2.255(2), d(Co1-Cl2) = 2.257(2), <(N1-Co1-N2) = 125.7(2), and <(Cl1-Co1-Cl2) = 119.44(6). (b)—a perspective view of the packing of the [Co(4MeO-L)₂Cl₂] molecules in the direction of the crystallographic b-axis. Observed π–π stacking interactions were visualized by depicting the shortest C···C distances (black dashed lines). The hydrogen atoms are omitted for clarity.
