Abstract
Three coordination polymers, [Cd(obtz)(NCS)2]
n
(1), [Cd(obtz)2(dca)2]n (2), and {[Cd(obtz)2(H2O)2]·(SiF6)}n (3), were synthesized using the flexible 1,2-bis(1,2,4-triazol-1-ylmethyl)benzene (obtz). In 1, obtz connects the [Cd(μ-NCS-N:S)2]n 2-D networks into an unusual 3-D cubic network. 2 is comprised of neutral 1-D double chains. Each chain forms π–π stacking interactions with four adjacent chains (two above and two below) to extend a 3-D supramolecular network. 3 consists of 1-D cation chains [Cd(obtz)2(H2O)2]n and . Three-dimensional supramolecular architecture is formed through hydrogen bond interactions between the coordination waters and uncoordinated 2-position nitrogens of obtz or
. Luminescence and thermal stabilities of 1, 2, and 3 were measured.
