Syntheses and structures of five cadmium(II) coordination polymers from 1,2-bis(1,2,4-triazol-l-yl)ethane

Five structually distinct coordination polymers {[Cd(bte)(3)](NO3}(n) (1), {[Cd(bte)(2)(H2O)(2)](NO3)(2)}(n) (2), {[Cd(bte)(NO2)(2)]}(n) (3), {[Cd(bte)(2)(H2O)(2)](H2O)(2)(ClO4)(2)}(n) (4) and [Cd(bte)(NCS)(2)](n) (5) (bte = 1,2-bis(1,2,4-triazol-1-yl)ethane) have been synthesized and characterized. The structures of 1, 2, 3, 4 and 5 consist of a double interpenetrating three-dimensional alpha-poloniumn cubic network, a two-dimensional (4,4) network, a two-dimensional rhombic network, a one-dimensional double chain containing 18-membered [Cd-2(bte)(2)] rings and a two-dimensional rhombic network containing eight-membered [Cd-2(SCN)(2)] rings, respectively.
