Source of material

The organic compound oxide azobenzene 2,2′,3,3′-tetracarboxyl acid (abbreviated as H4Oobtc) was synthesized with the help of Jinan Camolai Trading Company of Shandong, China, and 1,2-bis(4-pyridine) ethylene (abbreviated as bpe) was purchased from TCI chemicals. In a representative experiment, Co(CH3COO)2⋅4 H2O (0.2 mmol, 0.049 g), H4Oobtc acid (0.1 mmol, 0.038 g) and bpe (0.1 mmol, 0.019 g) were mixed and dissolved in 30 mL aqueous solution of ethanol-water (V/V = 1 : 1) and then the mixture was adjusted to neutral with KOH (0.2 mol L−1). The solution was filtered after being stirred for 12 h at 120 °C. Two weeks later, pink block crystals of the title compound were obtained by the solvent evaporation approach. Yield: 31 mg (34% based on cobalt element). Elemental analysis (%) for C28H36N4O19Co2 (calcd. C 39.54, H 4.27, N 6.59; Found C 39.39, H 4.34, N 6.49.

Experimental details

Coordinates of hydrogen atoms were added at calculated positions. Their Uiso values were set to 1.2Ueq of the parent atoms. The atom O1 is half occupied to model a 1/1 disordered 3,3′-(1-oxidodiazene-1,2-diyl)diphthalate (Oaobtc).

Comment

Transition metal coordination polymers (CPs) have attracted great attention due to their intriguing architectures and potential applications. Among the organic linkers, polycarboxylic acids/polycarboxylates can bind several metal centers with specific coordination geometry to construct clusters and construct one to three dimensional compounds with interesting properties [4], [5], [6]. The chemical modified ligands, such as organic compounds containing an azo (—N=N—) group as light-harvesting chromophore are employed to enhance/reduce the light adsorption [7]. Synthesis, structural and magnetic studies of azido, and hydroxyl, chloride bridged Co(II) complexes have been used as models to understand the electron/charge transfer processes [8]. However, only a limited number of one dimensional cobalt coordination compounds based on multi-carboxylates have been characterized structurally. On the other hand, 1,2-bis(4-pyridine)ethylene (abbreviated as bpe) as a rigid N donor ligand has been proved to be a good candidate used as linker constructing coordination polymers in the field of potential functional materials [9]. In order to further study the coordination behavior and role of bpe in the self assembly processes [10] in the presence of substituted aromatic-heterocyclic acid, and to identify compounds that exhibit similar behavior as the 1D chain structure was associated with some moieties.

The asymmetric unit of title structure contains one Co(II), one half of a Oaobtc and one half of a bpe. As illustrated in the left part of the figure, cobalt(II) ion adopts six coordination fashions, showing a pseudo octahedral geometry with a N1O5 donor set around it. Among the donor set, the O6, O8 and O10 atoms from terminal H2O ligands, and another oxygen atoms of carboxylate moieties from Oaobtc, are located in equatorial plane. The N2 atom from bridging bpe and one O7 atom derivated from a coordinated water are located in axis positions, completing the octahedron coordination geometry. All four carboxylate groups Oaobtc link two adjacent Co(II) in mono dentate mode, in an anti-anti fashion. This coordination fashion is essentially different from the either transition metal complexes based on azobenzenetetracarboxylic acid and bis(imidazole) ligand [11] or the lanthanide complexes based azobenzenetetracarboxylic acid and DMF [12]. The average Co–O distances range from 2.0440(19) to 2.176(2) Å, while, bond Co–N distance is 2.115(2) Å, which are in the expected ranges [13], [14]. The bond angle involving Co(II) ranges from 83.51(8) to 173.40(7)°.

The ancillary ligand bpe links neighboring [Co(Oaobtc)H2O] units, with the Co⋯Co separation of 13.682 Å; Oaobtc and bpe ligands connect the [Co(H2O)4] units alternately into one-dimensional zigzag chains along the crystallographic bc plane (right part of the figure). In such a manner, fence-like bump stagger chain with water arms are generated, as displayed in right half of figure. Close inspection finds that there are strong hydrogen bond interactions between the oxygen atoms of carboxylates water. They are listed as follow, O10⋯H10B-O5 #1,#[O1-O5#1 = 2.687(3) Å, O1-H1⋯N1 = 151.6°], O3⋯H6A-O6, [O3-O6 = 2.687(3) Å, O3⋯H6A-O6 = 157.5°], O7⋯H7B-O4, [O7-O4 = 2.759(3) Å, O7⋯H7B-O4 = 158.8°], O8⋯H8B-O5 #2 , [O8⋯O5 #2 = 2.596(3) Å, O8⋯H8B-O5 #2 = 157.3°], O9⋯H9B-O3, [O9⋯O3 = 2.846(3) Å, O9⋯H9B-O3 = 143.2°]. Symmetry codes are #1 1 + X, −1 + Y, +Z; #2 1 − X, 1 − Y, 2 − Z. These hydrogen bonding parameters excellently reflect the hydrogen bond interactions contributing to packing crystal.
