Source of material

The reagents available commercially were used without further purification. 5-(Phenyldiazenyl)tropolone was synthesized according to the previously published method [3]. 5-(Phenyldiazenyl)tropolone (452 mg, 2.0 mmol) and pyridine (162 μL, 2.0 mmol) were added to a solution of Co(CH3COO)2⋅4H2O (249 mg, 1.0 mmol) in EtOH:H2O (40 ml, 1:1). The solution was refluxed (110 °C) for 7 days, filtered and allowed to crystallize. Crystals were obtained from the slow evaporation of the solution at room temperature (81% yield) within 2 weeks.

Experimental details

Methyl H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H = 0.95 Å and Uiso(H) = 1.2 Ueq(C). The highest (0.39e Å−3) and lowest (−0.30e Å−3) residual electron density peaks were located respectively at 0.69 Å from the C1 and 0.58 Å from the Co1 atoms.

Discussion

Past investigations have highlighted the fact that the tropolone-type ligands (TropH) are very effective chelating agents and have a wide range of chemical applications [1], [2], [3], [4]. The complexation of these ligands to transition metal centres is however not a novel notion, with the tropolonato anion forming a five-membered chelating ring resulting in a smaller bite angle than that of the β-diketonato analogues [1, 5] . These ligands are ideally suited to the formation of structures with higher coordination numbers, which has been ascribed to the planarity and compactness of the ligand [6].

Tropolonato compounds have been noted to have useful chemical properties that can be exploited for a wide variety industrial purposes. Examples include the use of Rh(I) tropolonates in the asymmetric hydrosilation of acetophenone, the use of Th(IV) tropolonates for extraction of thorium from other rare earth elements and the Re(I) analogues for model radiopharmeceutical application [7], [8], [9].

In contrast, an in-depth literature study revealed limited examples of cobalt tropolonato complexes, with the only notable occurance highlighting the use of cobalt(III) bistropolonates ([Co(Trop)2(L)]+) as potential hypoxia-selective cytotoxins [10]. This observation regarding the limited solid-state crystallographic properties of cobalt(II) tropolonato compounds lead to the investigation of the crystal structure of [Co(ph-azotrop)2(py)2].

The asymmetric unit of the title crystal structure consists of half of the [Co(ph-azotrop)2(py)2] complex. The cobalt atom is located on an inversion centre and is coordinated to both phenyl-azotropolonato and pyridine with the other half of the molecule being generated by symmetry. The environment around the cobalt(II) metal centre has a distorted octahedral geometry with the pyridine ligands in the axial position. The Co—O distances are 2.063(1) Å and 2.077(1) Å respectively with a Co—N distance of 2.157(1) Å. The O—Co—O bite angle was determined to be 77.80(4)°. The molecules are held together by a head-to-tail π⋯π stacking interaction involving the phenyl-azotropolonato ligands, with a distance of 3.638 Å between best planes defined by the ligands. While free phenyl-azotropone [3] was found to be essentially planar, the cobalt(II) complex displays bending and twisting of the phenyl-azotropolonato back-bone. In the structure of the title compound an additional π⋯π interaction was observed between pyridine ligands with a distance of 2.617 Å, generating a three-dimensional supramolecular network.
