Experimental details

The water H atoms were located in the difference fourier maps, and then refined with Uiso(H) = 1.2 Ueq(O). The remaining H atoms were placed in idealized positions with C⋯H and N⋯H bond lengths constrained to 0.93 and 0.86 Å, respectively, and Uiso(H) = 1.2 Ueq(carrier C or N atom).

Source of materials

All source materials (NaOH, CoSO4 and MoO3) were purchased from Sinopharm Chemical Reagent Co. Ltd.; 4-(5-(1H-1,2,4-triazol-1-ylmethyl)-1H-1,2,4-triazol-3-yl)pyridine (C9H7N7) was purchased from Jinan Camolai Trading Company. All chemicals of analytical grade were obtained from commercial sources and used without further purification. A mixture of C9H7N7 (1 mmol), CoSO4 (2 mmol), MoO3 (5 mmol), NaOH (20 mmol) and deionized water (20 mL) was placed in a 30-mL Teflon-lined stainless steel autoclave. Then the autoclave was sealed and heated to 170 °C under autogenously pressure for 72 h. After being slowly cooled to room temperature at a rate of 2 °C/h, colorless prismatic crystals were recovered by filtration, washed with distilled water and air dried.

Comment

In recent years, octamolybdate [Mo8O26]4− based polyoxometalates (POMs) are of interest for their structural diversity and coordination capability in high dimensional frameworks [3], [4], [5], [6], [7]. This family of compounds can be divided into eight types, α-, β-, γ-, δ-, ϵ-, ζ- and θ-isomers. The difference between them are the number of MoO4, MoO5, and MoO6 units contained in their structures. For example, the [α-Mo8O26] contains two MoO4 and six MoO6 units, the [β-Mo8O26] has eight MoO6 units, and the [γ-Mo8O26] includes two MoO5 and six MoO6 units. The MoO5 units in [γ-Mo8O26] allow additional N or O atoms to occupy the vacancies of the Mo atoms to form [γ-Mo8O26N2] and [γ-Mo8O28] units. The organic moieties play an important role in adjusting the structures of the inorganic-organic compounds. To enrich this family of compounds, we introduce a new type of N-donor ligand 4-(5-(1H-1,2,4-triazol-1-ylmethyl)-1,2,4-triazol-3-yl)pyridine (C9H7N7) in our experiment.

The asymmetric unit of the title structure contains one Co(C9H7N7)2(H2O)2 one half (γ-Mo8O26)(C9H7N7)2 and four water molecules. The title compound is an addition compound. The upper part of the figure shows the mononuclear cobalt(II) complex. The γ-Mo8O26 is composed of six MoO6 octahedra interlinked along edges and two MoO5 pentahedra each sharing two edges with two C9H7N7 ligands. Such an arrangement produces four kinds of O atoms: two μ4-O with Mo⋯O distances of 1.9550(19)–2.4202(19) Å, four μ3-O oxygen atoms with Mo⋯O distances of 1.871(2)–2.3693(19) Å, six μ2-O oxygen atoms with Mo⋯O distances of 1.749(2)–2.332(2) Å, and 14 terminal oxygen atoms with Mo⋯O distances of 1.689(2)–1.724(2) Å. It should be mentioned that two Mo atoms are five coordinate and thus allowing additional N or O atoms to occupy the vacancies of the Mo atoms, which is the characteristic of γ-octamolybdate. In the title compound isoquinoline molecules act as ligands, Mo3 coordinating Mo3 (Mo3⋯N = 2.273(2) Å) to build the (γ-Mo8O26)(C9H7N7)2 coordination moiety (cf. the figure) which are comparable to other reported γ-octamolybdates [8, 9] .

An interesting feature of this structure is that the organic ligands are found in two tautomeric forms. In the cobalt(II) complex the ylidic form is preferred as two nitrogen atoms of adjacent five membered rings coordinate the Co(II) metal (cf. the upper figure). In the octamolybdate moiety the coordination is done by two pyridinyl moieties (cf. the lower figure).
