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′-(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. [ABSTRACT FROM AUTHOR]
