Source of material

A mixture of K4[GeW12O40] ⋅ 14H2O (0.1 mmol), CuCl2 ⋅ 2 H2O (0.2 mmol), 4,4′-dipyridylamine (0.1 mmol), 2,2′-bipyridine (0.1 mmol), and H2O (10 mL) was stirred for 30 min at 25 °C, after the pH value of the solution was adjusted to 5.0 with diluted NaOH solution and then transferred to a 23 mL Teflon-lined stainless steel reactor. The solution was heated under autogenous pressure at 160 °C for 96 h. After the solution was slowly cooled to room termperature at a rate of 10 °C h−1, blue block-shaped crystals were filtered off, washed with distilled water and dried in air.

Experimental details

The Olex2 program equipped with SHELXT and SHELXL were used for structure analysis [1], [2]. All the non-hydrogen atoms were located by SHELXT directly and refined anisotropicly by SHELXL with least squares methods. All the hydrogens on N and C were placed at calculated positions (0.93 Å) and refined with the riding model, with Uiso(H) set to 1.2 Ueq(C) or 1.2 Ueq(N). The H atoms of the solvent water molecule were located from the difference Fourier map and then allowed to ride on their parent O atom in the final cycles of refinement with d(O–H) = 0.850 Å and Uiso(H) = 1.5 Ueq(O). The occupancies of water molecules were refined as 0.5.

Comment

The significant contemporary interest in the crystal engineering of inorganic-organic hybrid materials not only originates from their diversely structural flexibility, but also from their widely promising potential applications in catalysis, medicine, photochemistry and electromagnetism [3], [4], [5]. Up to now, although a number of inorganic-organic hybrid compounds containing polyoxomolybdates have been reported [6, 7] . Design and synthesis of novel hybrid materials with highly specific and cooperative functions are still a challenging work. A widely used approach to the synthesis of these materials is the hydrothermal crystallization in the presence of organic amines, which are used as templates or structure-directing agents to facilitate the formation of various networks [8, 9] .

The title crystal structure is composed of [GeW12O40]4− Keggin-type polyoxoanions, [Cu(C10H8N2)(C10H10N3)2]4+ copper complex cations and water molecules. The polyoxoanion [GeW12O40]4− is a well known α-Keggin structure composed of 12 corner- or edge-sharing WO6 octahedra with the central germanium ordered and coordinated to four oxygen atoms in a tetrahedral fashion (cf. the figure). The Ge—O distances are in the range of 1.708(9)–1.718(11) Å and the O—Ge—O angles are in the range of 108.9(5)–110.5(5)°. The W—O distances can be grouped into three sets according to the kind of oxygen atoms bound to the tungsten atoms: W—Ot = 1.681(12)−1.726(13) Å, W—Ob = 1.877(12)−1.964(11) Å and W—Oc = 2.291(12)−2.331(12) Å. The O—W—O angles are between 71.2(5) and 170.6(5)° and are in accord with the literature [10]. In the copper complex [Cu(C10H8N2)(C10H10N3)2]4+, each of the Cu2+ is six-coordinated by two nitrogen atoms from two 4,4′-dipyridylaminium cations (dpa) (N3 and N6), two nitrogen atoms from one 2,2′-bipyridine molecule (bipy, N1 and N2) and two oxygen atoms from adjacent POMs anions (O24 and O32), respectively, resulting a distorted octahedral geometry. The Cu—O distances were in the ranges of 2.412(13)−2.833(14) Å, and the Cu—N distances ranges from 1.982(16) to 2.026(14) Å. The dpa and bpy molecules act as a monodentate and bidentate ligand respectively coordinated to a copper atom with its nitrogen atoms. The most remarkable structural feature of the title compound is that the adjacent Keggin [GeW12O40]4− clusters are interconnected through [Cu(C10H8N2)(C10H10N3)2]4+ bridging groups to form a one-dimensional infinite anionic chain (cf. the figure; dashed lines). Furthermore, the adjacent one-dimensional chains are linked up by extensive hydrogen bonding interactions of the polyoxoanions, 4,4′-dipyridylamine, 2,2′-bipyridine and lattice water molecules to form a three-dimensional supramolecules framework. There are three types of intermolecular hydrogen bonds (O—H⋯O, C—H⋯O, N—H⋯O).
