title: Poly[(μ3-benzene-1,4-diacetato)[μ2-1,4-bis(1,2,4-triazol-1-yl)butane]cadmium(II)]: self assembly into a three-dimensional supramolecular framework based on [Cd(μ3-benzene-1,4-diacetate)] double chains.
abstract: The title compound, [Cd(C(10)H(8)O(4))(C(8)H(12)N(6))](n), crystallizes with an asymmetric unit comprising a divalent Cd(II) atom, a benzene-1,4-diacetate (PBEA(2-)) ligand and a complete 1,4-bis(1,2,4-triazol-1-yl)butane (BTB) ligand. [Cd(PBEA)](n) double chains, arranged parallel to the c axis, are formed through an exo-tridentate binding mode of the PBEA(2-) ligands. These [Cd(PBEA)](n) double chains are pillared by tethering BTB ligands, in which the BTB shows a trans-trans-trans conformation, to establish [Cd(PBEA)(BTB)](n) two-dimensional coordination polymer (4,4)-layer slab patterns. The three-dimensional supramolecular architecture is formed by C-H···O hydrogen bonds and C-H···π interactions.
