Five coordination complexes [Cd(hbmb)(tbi)]_n (1), [Cd(hbmb)(adi)]_n (2), [Zn(hbmb)_0.5(atda)]_n (3), {[Zn₂(hbmb)(suc)_1.5(OH)]¡¤2H₂O}_n (4), and {[Zn₂(hbmb) (fum)_1.5(OH)]¡¤2H₂O}_n (5) (H₂tbi = 5-tert-butylisophthalic acid, H₂adi = adipic acid, H₂atda = 1,3-adamantanediacetic acid, H₂suc = succinic acid, H₂fum = fumaric acid, hbmb = 1,1¡ä-(1,6-hexane)bis-(2-methylbenzimidazole)) have been hydrothermally synthesized and structurally characterized. Complex 1 is an undulated 2D structure with (6³)₂ topology, containing left- and right-handed helical chains. Complex 2 possesses a puckered two-dimensional (2D) network with 4⁴¡¤6² topologies symbol. Complex 3 exhibits a 2D (4, 4) parallelogram network and also owns left- and right-handed helical chains. Complexes 4 and 5 display 2D rectangular grids and can be simplified as a four-connected 4⁴¡¤6² topological network. Moreover, the photoluminescence properties and thermal stabilities of the five complexes were investigated.
