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

The title compound, [Cd(C₁₀H₈O₄)(C₈H₁₂N₆)]_n, crystallizes with an asymmetric unit comprising a divalent Cd^II atom, a benzene-1,4-diacetate (PBEA²⁻) 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 PBEA²⁻ 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.
