title: The infinite double-stranded chain polymer catena-poly[[bis(dicyanamido)zinc(II)]-di-mu-1,2-bis(1,2,4-triazol-1-yl)ethane-kappa4N4:N4'].
abstract: The coordination geometry of the Zn(II) atom in the title complex, [Zn(C(2)N(3))(2)(C(6)H(8)N(6))(2)](n) or [Zn(dca)(2)(bte)(2)](n), where bte is mu-1,2-bis(1,2,4-triazol-1-yl)ethane and dca is dicyanamide, is distorted compressed octahedral, in which the Zn(II) atom lies on an inversion center and coordinates four N atoms from the triazole rings of four symmetry-related bte ligands and two N atoms from two symmetry-related monodentate dca ligands. The structure is polymeric, with 18-membered spiro-fused rings extending in the b direction and each 18-membered ring involving two inversion-related bte molecules.
