Source of material

All chemical reagents were used without further purification. The 3-nitrobenzene-1,2-dicarboxylic acid were purchased from Beijing Bailingwei Technology Co., Ltd. 3,5–Bis(1-imidazolyl)pyridine was bought from Jinan Henghua Technology Co., Ltd. All other chemical reagents were of analytical grade and obtained from the Tianjin Deen Chemical Reagent Co., Ltd. The mixture of 3-nitrobenzene-1,2-dicarboxylic acid (H23–Nbdc 21.4 mg, 0.1 mmol), 3,5-bis(1-imidazolyl)pyridine (bip, 21.1 mg, 0.1 mmol), Cd(OAc)2·2H2O (26.7 mg, 0.1 mmol), NaOH (4 mg, 0.10 mmol) and H2O (6 mL) was placed in a 23 ml Teflon-lined autoclave at 393 K for four days, then cooled to room temperature. Colorless block crystals were obtained in ca. 62% yield. Elemental analysis calcd. (%) for C30H25N11O8Cd: C, 46.20; H, 3.23; N, 19.75 Found: C, 46.24; H, 3.28; N, 19.68.

Experimental details

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. Hydrogen atoms were placed in their geometrically idealized positions and constrained to ride on their parent atoms. The U iso of the H-atoms were constrained to 1.2 times U eq of their bonding carbon atoms with C–H = 0.93 Å (aromatic) and 1.5 times U eq for the hydrogen atoms at water with O–H = 0.85 Å. The O4 and O5 atoms were disordered and the components of disordered atoms were refined isotropically.

Comment

Metal-organic Complexes have always been in the spotlight for a long time not only for their diversities of structures [5], [6], [7], [8], but also for their strong thermal and chemical stabilities [9], [10], [11], [12]. At the same time, they have attractive application prospects in many fields such as gas storage/separations, fluorescent sensing, nonlinear optics, magnetic, catalysis, and so on [13], [14], [15], [16]. Carboxylate ligands with the electron-withdrawing group (–NO2) are widely used as an oxygen-donor ligand because the N and O atoms in the –NO2 group can not only serve as coordination sites but also as acceptors for hydrogen-bonds to enrich the structural and functional diversities of coordination polymers [16]. In our previous work, we had synthesized a series of metal-organic compounds with diverse structures and excellent properties such as magnetism, fluorescent, photochemical and photocatalytic properties based on 3-nitrophthalic acid [17], [18], [19] and 4-nitrophthalic acid [16, 20–22]. Among the N-donor ligands, the imidazolyl ligands are the most common N-donor ligands to combine with O-donor ligands to adjust the structures and properties of metal-organic complexes [23]. The 3,5-bis(1-imidazolyl)pyridine (bip) is one of many imidazolyl N-donor ligands which were used to synthesize metal-organic complexes [24], [25], [26], [27]. In this study, we selected the 3-nitrobenzene-1,2-dicarboxylic acid (H23–Nbdc) as an educt, 3,5-bis(1-imidazolyl)pyridine (bip) as a N-donor ligand, cadmium acetate as Cd-metal supplier to obtain the coordination polymer.

The single-crystal X-ray analysis shows that the title complex crystallizes in orthorhombic crystal system and features a one-dimensional chain. The asymmetric unit contains a half Cd(II) ion, a half 3–Nbdc dianion, one bip molecule, and one guest water molecule, as shown in the figure (A: x, 0.5 − y, z; B: 0.5 + x, y, 1.5 − z; C: 0.5 + x, 0.5 − y, 1.5 − z). The Cd(II) ion is seven coordinated by three oxygen atoms and four nitrogen atoms. Among them, three oxygen atoms are from two symmetry-related 3–Nbdc dianions, and the other four nitrogen atoms are from three symmetry-related bip ligands. The seven-coordinated Cd(II) ion forms a slightly distorted single cap octahedral [CoN4O3] geometry with the four atoms (N1, N1A, N4B, N4C) in the equatorial plane and the other three atoms (O1, O1A, O3B) in the axial position (see the Figure). The Cd–O bond lengths are 2.551(2) and 2.543(2) Å, whilst the Cd–N bond lengths are 2.317(2) and 2.3304(19) Å, respectively. The bond angles around the Cd centers range from 50.02(10) to 164.94(7)°.

The two carboxyl groups of one 3–Nbdc anion adopt chelating-bidentate and monodentate coordination modes, respectively. Every two cadmium atoms are linked together through one 3–Nbdc dianion and two bip molecules by an external single bridging coordination mode to form a chain with the Cd⃛Cd distance of 9.1213(1) Å. Adjacent chains are linked through hydrogen bonds between free water oxygen atom and nitrogen atom from bip molecules (O(1W)–H(1WB)⃛N5: d = 2.22 Å) along the c direction to generate a two-dimensional layer with the nearest Cd⃛Cd separation of 9.5619(2) Å. The adjacent layers stack together in a –ABAB-sequence to achieve a whole three-dimensional supramolecular structure via very weak interlayer π-π interactions between pyridine ring and imidazole ring of bip ligands. The centroid-centroid distance and the dihedral angle between pyridine ring and imidazole ring are 3.9677(0) Å and 15.9°, respectively.
