Abstract A series of zinc(II) coordination complexes, formulated as {[Zn (dbim)1.5 (m-H2adica)]n·2H2O}n (1), [Zn (dbim) (H2adi)]n (2), [Zn (dbim) (m-H2bdc)]n (3), [Zn0.5 (dbim)0.5 (p-H2bdc)0.5]n (4), [Zn (dbim) (H2sdba)]n (5) and [Zn (dbim)0.5(H2atda)]n (6) (dbim = 1-(4-((2,5-dimethyl-3aH-benzo [d]imidazole-1 (7aH)-yl)methyl)benzyl)-3a,7a-dihydro-2,5-dimethyl-1H-benzo [d]imidazole, m-H2adica = 1,3-adamantanedicarboxylic acid, H2adi = adipic acid, m-H2bdc = 1,3-benzenedicarboxylic acid, p-H2bdc = 1,4-benzenedicarboxylic acid, H2sdba = 4,4′-sulfonyldibenzoic acid, H2atda = 1,3-adamantanediacetic acid), have been obtained by hydrothermal reactions. Complex 1 features a 1D step-like chain. Complex 2, 3 and 4 exhibits a 4-connected 2D topology with a point symbol of 44·62, severally, while complex 5 possesses a 4-connected 2D topology with the point symbol of (3·43·52) (44·62). Complex 6 is a 1D chain structure. Additionally, complexes 1–6 present different photoluminescence behaviors in the solid state.
