Three position isomers 1,2-, 1,3-, 1,4-benzenedicarboxylate and 1,4-bis(1,2,4-triazol-4-yl)benzene were used to assembly zinc(II) coordination polymers {[Zn 2 (btx) 0.5 (1,2-bdc) 2 (H 2 O)]·H 2 O} n (1), {[Zn(btx)(1,3-bdc)]·2H 2 O·(DMF)} n (2) and {[Zn(btx)(1,4-bdc)]·3H 2 O} n (3). 1 is a (3,4,4,4)-connected two-dimensional network with point symbol (4 2 ·6)(4 4 ·6 2 )(4 3 ·6 2 ·8)(4 2 ·6·10 3 ). 2 shows a two-dimensional (4,4) network. 3 exhibits a 5-fold interpenetrated three-dimensional diamondoid network. The structural versatility shows that the structures of coordination polymers can be tuned by the position isomers ligands. The luminescence and thermal stability were investigated.
