1 Source of materials

5-[(Pyridin-4-yl-methyl)amino]isophthalic acid (C14H12N2O4, H2L) was synthesized following the literature reported by us. 4 Both the analytical-grade N,N-dimethylformamide (DMF) and cadmium chloride hemipentahydrate (CdCl2·2.5H2O) were commercially available and were utilized without further purification. The title compound was solvo/hydrothermally synthesized using the following procedure. 0.2 mmol (0.0544 g) of H2L, 1 ml of DMF, 5 ml of distilled water and 0.2 mmol (0.457 g) of CdCl2·2.5H2O were added to a 15 ml Teflon reaction vessel and then sonicated for 10 min, resulting in a white suspension liquid. The Teflon-lined stainless steel reaction vessel was sealed and heated at 110 °C for 136 h. Upon cooling to room temperature, a large amount of colorless rod crystals were obtained with a yield of 73 % based on CdCl2·2.5H2O after being isolated by filtration, washed with the N,N-dimethylformamide/water mixture and dried at room temperature.

2 Experimental details

The structure was solved by Direct Methods by SHELXT program and refined by SHELXL program. All H-atoms bound to the C atoms were positioned with idealized geometry and refined isotropically with U iso(H) = 1.2 times U eq(C) using a riding model with C–H = 0.93 Å for aromatic H atoms and C–H = 0.97 Å for methylene H atoms. The H-atoms (H1w, H2w, H13, and H7) from O and N atoms were positioned with Q peaks and refined isotropically with U iso(H) = 1.5 times U eq(O) or U iso(H) = 1.2 times U eq(N).

3 Comment

At present, the use of diverse polydentate ligands containing rich N/O coordinating atoms is preferred in the design and synthesis of metal coordination polymers including metal-organic frameworks because they generally can provide multiple coordination sites and exhibit various coordination geometries. 5 , 6 , 7 In the past two decades, as a flexible organic polydentate ligand, 5-[(pyridin-4-yl-methyl)amino]isophthalic acid (H2L) has been selected to synthesize many interesting metal coordination polymers with some fascinating structural architecture. 8 , 9 , 10 , 11 The Cd(II) atom as the coordination center is a usual choice in the construction of metal coordination polymers, however, these reported metal coordination polymers based on H2L-related ligand, including our previously reported Cd–MOF [Cd(L)]·(DMF)(H2O), 12 are three-dimensional in the crystal structure. Herein, we obtained the first example of one-dimensional Cd(II) coordination polymer when using H2L as organic ligand through a solvo/hydrothermal method.

The asymmetric unit consists of one half of a Cd(II), one HL − anion, and one coordinated water molecule. Each Cd(II) atom is six-coordinated with two pyridine nitrogen atoms from two HL − ligands and four oxygen atoms from another two HL − ligands and two coordinated water molecules, which results in a slightly distorted octahedral geometric configuration {CdO4N2}. The Cd–N and Cd–O lengths are in the ranges of 2.317(2) Å and 2.3182(19)–2.3193(19) Å, respectively. These bond distances are in agreement with these previously reported cadmium coordination polymers. 13 In the title compound, the HL − ligand serves as a μ 2-bridge linking two adjacent Cd(II) atoms with its pyridine nitrogen atom and one carboxylate oxygen atom, where the dihedral angle between benzene ring and pyridine ring is 116.57°. Pairs of HL − ligands connect symmetry-related Cd(II) atoms through monodentate carboxylate O and pyridine N atoms with the Cd⋯Cd separation of 12.160(10) Å to form one-dimensional loop-like chain. An infinite three-dimensional supramolecular structure in the title compound was further formed from the one-dimensional loop-like chains and stabilized through hydrogen bonding and π–π stacking interactions. The distance between the benzene rings of two adjacent HL − ligands is 3.3599(12)–3.4205(12) Å, indicating the presence of π–π stacking interactions. Rich hydrogen bonding interactions include an intramolecular hydrogen bond (O5–H1w⋯O4) and intermolecular hydrogen bondings (O5–H2w⋯O3A, N2–H7⋯O4B, O2–H13⋯O1C).
