Source of material

Terephthalic acid (0.017 g, 0.1 mmol), 1,2,4,5-tetrakis-(1,2,4-triazol-1-ylmethyl)-benzene(0.04 g, 0.1 mmol) and Cadmium(II) acetate (0.023 g, 0.1 mmol) were added to the mixture of water (7 mL) and 1,4-dioxane (1 mL) in a Teflon-lined stainless steel reactor. The mixture was heated at 403 K for three days, and then slowly cooled down to room temperature. Colorless crystals of the title compound were obtained.

Experimental details

The crystallographic data of title complex was collected on a Rigaku Saturn 724 CCD diffractometer at room temperature. Absorption corrections were applied by using multi-scan program [1]. Using Olex2 [2], the structure was solved with the ShelXT [3] structure solution program using Intrinsic Phasing and refined with the ShelXL [4] refinement package. The H atoms bonded to C atoms were fixed, with C–H distance of 0.93 Å; and/or positioned geometrically in the riding-model approximation; U iso(H) = 1.2U eq(C), U iso(H) = 1.5U eq(O).

Comment

In order to obtain unique Metal Organic Frameworks (MOFs) with interesting properties, many flexible ligands have been widely employed as linkers of metal ions, specifically flexible N-donor bridging ligands [5], [6], [7], [8]. For example, 1,2,4-triazole and its derivatives as high versatile organic linkers can combine the advantages of coordination geometries of both pyrazole and imidazole. To date, there are a great number of MOFs based on flexible bis(triazole) or tri(triazole) ligands, such as 1,4-bis(1,2,4-triazol-1-ylmethyl)benzene or 1,3,5-tris(1,2,4-triazol-1-ylmethyl)-2,4,6-trimethylbenzene, but the MOFs built by flexible tetra(triazole) ligands are relatively limited [9], [10], [11], [12]. The combination of N/O-donor ligands should better satisfy the coordination needs of metal ions and change the dimensionality [13], [14], [15], [16], [17]. On the basis of the above considerations, we choose the flexible tetrapodal 1,2,4,5-tetrakis(1,2,4-triazol-1-ylmethyl)-benzene (ttyb) as a functional ligand and employ “mix-ligand” synthetic strategy to explore the assembly with “mixed” ttyb and aromatic polycarboxylate ligands. In this context, we reacted ttyb with Cd2+ ions, then employed terephthalic acid/terephthalate (PTA) ligand as an auxiliary ligand, which features one two-dimensional structure, namely [Cd(PTA)(ttyb)0.5(H2O)].

X-ray analysis reveals that title complex I crystallizes in monoclinic space group P21/c. The asymmetric unit of title complex contains one independent Cd(II) cation, one PTA2− anion, one coordinated H2O and one half of a ttyb ligand. Each Cd center is five coordinated by three carboxylic O atoms from three PTA2− anions, one N atoms from ttyb ligand and one water molecules to form a slight distorted trigonal bipyramidal geometry. The completely deprotonated PTA2− ligand, in which one carboxylate group adopts the bidentate chelate mode and the other adopts monodentate mode, acts as a μ2 bridging ligand two Cd(II) ions. The PTA2− ligands link the Cd(II) via Cd–O coordination interactions to give a 2D network with Cd2(COO)4 subunits. ttyb acts as μ2-bridge linking two Cd(II) ions, and cannot connect the 2D layer to extend to a 3D network. The Cd–O lengths are in the range of 2.2089(18)–2.369(2) Å. The Cd–N lengths are 2.235(2) Å. Comparing I with {[Cd2(L)2(SO4)2(H2O)]2H2O}n (II, L = 1,2,4,5-tetrakis(imidazol-1-ylmethyl)benzene) [9], both of which prepared from the similar starting reactants, some important similarities and differences can be found as follows: (i) The coordination mode of tetradentate ligands. In I, ttyb acts function as a bidentate ligand to coordinate two Cd atoms using two flexible arms containing N atoms, another two 1,2,4-triazol groups do not take part in the coordination. In II, there are two ligands L (LA and LB) with different conformations in the asymmetric unit of II. Ligand LA serves as a tetradentate ligand to coordinate with four Cd atoms and ligand LB acts as a bidentate ligand to coordinate two Cd atoms. (ii) Different conformations of the tetradentate ligands. In I, ttyb adopts an up,up,down,down-conformation. In II, LA has an up, down, down, up-conformation and ligand LB adopts a peculiar H-type conformation. Subsequent studies about this flexible tetrapodal ligand are underway. Many further attempts on developing new complexes with ttyb as the first ligand, such as by the use of other solvents, introducing other N/O-donor bridging or polycarboxylate ligands have been implemented in our laboratory.
