Nine Cd(II) coordination polymers {[Cd(bte)(NO2-bdc)(H2O)]·H2O}n (1), {[Cd(bte)(I-bdc)(H2O)]·H2O}n (2), {[Cd(bte)0.5(OH-bdc)(H2O)]·H2O}n (3), {[Cd(bte)2(H2O)2]·(SO3-Hbdc)·4H2O}n (4), {[Cd(bte)0.5(1,4-bdc)(H2O)]·2H2O}n (5), {[Cd2(bte)2(btec)(H2O)2]·11H2O}n (6), [Cd(btre)(obc)2]n (7), {[Cd(btre)0.5(NO2-bdc)(H2O)2]·H2O}n (8) and {[Cd3(btre)2(SO3-bdc)2]·4H2O}n (9) (bte = 1,2-bis(1,2,4-triazol-1-yl)ethane, btre = 1,2-bis(1,2,4-triazol-4-yl)ethane, NO2-bdc = 5-nitroisophthalate, I-bdc = 5-iodoisophthalate, OH-bdc = 5-hydroxyisophthalate, SO3-bdc = 5-sulfoisophthalate, 1,4-bdc = 1,4-benzenedicarboxylate, btec = 1,2,4,5-benzenetetracarboxylate, obc = 4-hydroxybenzenecarboxylate) have been synthesized and structurally characterized. 1 and 2 are independent 1D MONTs. An interesting structural feature of 1 and 2 is that the NO2 or I groups of each 1D MONT polythread into two adjacent 1D MONTs to form a (1D → 2D) polythreaded array. 3 is a (3,4)-connected 2D network with the point symbol (42·6)(42·63·8). 4 shows the double chain cation [Cd(bte)2(H2O)2]n2n+ and 3D hydrogen bond architecture. The structure of 5 is an unusual (4,4)-connected 3D network with the point symbol (4·6·84)(4·63·82)2. 6 is an unusual (3,4)-connected 3D network with the point symbol (83)2(86). The structures of 7 and 8 are the 1D chain and 1D ladder, respectively. 9 exhibits an unusual (3,5,5,6)-connected three-dimensional network with the point symbol (42·8)2(43·83·103·12)2(43·6·83·103)2(44·63·86·102). The luminescence and thermal stability of 1–9 were investigated.
