The asymmetric unit of the title compound, (C12H12N2)3[V10O28]·2H2O, contains one half of a deca­vanadate anion, one and a half trans-1,2-bis­(4-pyridinio)ethene cations and one water mol­ecule. The V10O28 groups are involved in a three-dimensional hydrogen-bonding network through Ow—H⋯O, N—H⋯O and C—H⋯O inter­actions.

Comment top

The title compound was synthesized as part of our studies focused on the construction of new inorganic-organic vanadates (Zavalij & Whittingham, 1999) with first row transition metal centres (Fernández et al., 2009b). The pyridyl ligands have very often used since they have two nitrogen atoms that can bridge metal atoms to form polymeric compounds (Fernández et al., 2009a), (Khan et al., 2004), (Zheng et al., 2001). However, the hydrothermal synthesis of the Co/Bpe/VxOy system give rise to the crystallization of the title compound as a minor product of the reaction.

The polyoxovanadates exhibit interesting physical and chemical properties with relevance to catalysis, biochemical processes (enzyme inhibitor or activator), medicine, and material science (Pope & Muller, 1991, 1994; Rhule et al., 1998).

The asymmetric unit of (I) consists of one-half decavanadate anion, one and a half pyridinium cations and one water molecule. The decavanadate anion is composed of ten VO6 octahedra combined via shared edges and corners. Six octahedra are arranged in a 2 x 3 equatorial plane sharing edges; the other four octahedra are distributed above and below the equatorial plane, connected by shared sloping edges with the central six octahedra (Fig. 1).

The V—O bond lengths are classified according to the coordinative conditions of the oxygen atoms: terminal O atoms (V═O, 1.597 (2) - 1.608 (2) Å); double-bridging O atoms (V—O, 1.684 (2) - 2.083 (2) Å), triply bridging O atoms located on the surface of the [V10O28]6- cluster (V—O, 1.968 (2) - 2.061 (2) Å), and one six-coordinate O atom (V—O 2.085 (2) - 2.344 (2) Å).

The supramolecular structure is formed by Ow—H···O, N—H···O and C—H···O hydrogen bonds, between the anion and the water molecules, between the cation and the anion, and between cation and water molecule (Steiner, 2002).

The decavanadate anions are hydrogen bonded through two water molecules (Fig.2) forming chains in the [010] direction (Fig. 1). The N—H groups of the organic cations interact with the surface oxygen atoms of the decavanadate anion (N1—H21···O9, N2—H22···O2, N3—H23···O5). Each V10O28 anion is linked trough three organic cations to other two V10O28 anion (Fig. 2). The hydrogen bonding trough the water molecules (O—H···O) and organic cations (N—H···O) of the [V10O28] clusters, generates the layers shown in the figure 2. The layers are stacked along the [101] direction via C—H···O hydrogen bonds, establishing the three dimensional supramolecular network (Fig. 3).

Experimental top

A mixture consisting of NaVO3 (0.135 mmol), 1,2-di(4-pyridyl)ethylene (0.135 mmol), Co(NO3)2.6H2O (0.135 mmol), and H2O (30 ml) in the molar ratio 1:1:1 was placed in a 50-ml Parr Teflon-lined autoclave. The initial pH value was adjusted to 4.0 with a 1M HNO3 solution under a vigorous stirring. The autoclave was sealed and heated for 3 days at 120°C. After the reaction a mixture of dark brown polycrystalline powder with a minor percentage of the title compound orange single crystals were obtained. In order to obtain the title compound as a single phase, the Co(NO3)2.6H2O was suppressed from the initial reactants. However, all attempts to obtain the title compound as a single phase after the hydrothermal reaction have been unsuccessful.

Refinement top

The H atoms belonging to the organic ligand were placed at geometrically idealized positions (C—H = 0.93 Å and N—H = 0.86 Å) and constrained to ride on their parent atoms [Uiso(H)= 1.2Ueq(C,N)]. H atoms of the water molecule were located in a difference map and refined with O—H inter-atomic distances restrained to 0.93 Å, with the standard deviation set at 0.01 Å.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
