The reaction of a ditopic diiminopyridine ligand 2,6-bis(1-(2,6-diisopropyl-4-(pyridin-3-yl)phenylimino)ethyl)pyridine (L) with group 12 metal salts in various solvent systems afforded 12 metal−organic coordination complexes, including zero-dimensional (0D) metallomacrocycle, one-dimensional (1D) chain, and two-dimensional (2D) network structures: [Zn4Cl8L2]·2C7H8·2CH3COCH3·3H2O (1a), {[Zn2Cl4L]·2CH3OH·2CHCl3·2H2O}n (1b), {[ZnCl2L]·0.5CH2Cl2·0.5H2O}n (1c), {[ZnBr2L]·CH2Cl2}n (2), [ZnI2L]n (3), {[Zn(NO3)2L2·2C7H8]}n (4), {[CdCl2L2]·2CH2Cl2}n (5), {[Cd(NO3)2L2]·CH2Cl2}n (6), {[Cd(ClO4)2L2]·CH2Cl2}n (7), {[Hg4(μ2-L2)(μ2-Cl2)(μ-HgCl2)Cl6]·2H2O}n (8), {[HgBr2L]·CH3CN·0.5CH2Cl2}n (9), and {[HgI2L]·0.5CH2Cl2}n (10). In these complexes, the semirigid ligand L exhibits four kinds of coordination modes [(syn, syn, syn), (syn, syn, anti), (anti, anti, syn), (anti, anti, anti)], leading to the formation of various supramolecular structures. Complex 1a is a tetranuclear metallomacrocycle. 1b contains 1D zigzag chains ...
