The asymmetric unit of the title compound, (C12H16N3O)2[PdCl4]3, consists of a 4,4′-(1-aza­niumyl-2-hy­droxy­ethane-1,2-di­yl)dipyridinium dication and one and a half tetra­chloridopalladate(II) anions; the latter has inversion symmetry. In the cation, the pyridinium rings attached to the central 1-aza­niumyl-2-hy­droxy­ethane fragment show an anti conformation, as indicated by the central C—C—C—C torsion angle of −178.1 (4)°, and they are inclined to one another by 25.7 (2)°. In the crystal, the cations and anions are linked through N—H⋯Cl and O—H⋯Cl hydrogen bonds. There are also π–π contacts [centroid–centroid distance = 3.788 (3) Å] and a number of C—H⋯O and C—H⋯Cl inter­actions are present, consolidating the formation of a three-dimensional structure.

Comment top

Hydrogen bond based organic–inorganic hybrid materials are receiving continuous interest because of their structural, magnetic, optical and electrical properties (Yao et al., 2010; Sanchez et al., 2011; Pardo et al., 2011). An interesting approach for the preparation of such materials consists in the utilization of supramolecular synthons containing charge-assisted N+–H···Cl- hydrogen bonds, through which organic cations and anionic metal complexes are linked to form crystalline organic–inorganic hybrid solids (Kumar et al., 2006; Adams et al., 2005,2006; Maris, 2008). As a further contribution we report herein on the crystal structure of the title compound.

The asymmetric unit of the title compound consists of one threefold charged organic cation in a general position and two independent [PdCl4]2- dianions, one of which is located on a crystallographic inversion center (Fig. 1). In the cation, the pyridinium rings attached to the central 2-ammoniumethanol fragment show an anti conformation, as indicated by the C8—C1—C2—C3 torsion angle of -178.1 (4)°, and form a dihedral angle of 25.7 (2)°. The Pd atoms have square-planar coordination environments with Pd—Cl distances ranging from 2.2760 (10) to 2.3056 (11) Å.

In the crystal, the cations and anions are linked by N+—H···Cl- and O—H···Cl- hydrogen bonds (Table 1 and Fig. 2). There are π—π interactions present involving inversion related pyridinium rings [Cg···Cgi distance = 3.788 (3) Å; Cg centroid of the N3,C3-C7 ring; symmetry code (i) -x, -y+2, -z]. There are also a number of C-H···O and C-H···Cl interactions present, consolidating the formation of a three-dimensional structure (Table 1 and Fig. 2).

Experimental top

The organic entities in the title compound are the product of partial hydrolysis starting from 2,4,5-tris(pyridin-4-yl)-4,5-dihydro-1,3-oxazole, which was synthesized according to a previously reported procedure (Campos-Gaxiola et al., 2012). For the preparation of the palladium complex, a solution of 2,4,5-tris(pyridin-4-yl)-4,5-dihydro-1,3-oxazole (0.05 g, 0.16 mmol) in methanol and concentrated HCl (37%, 3 ml) was added dropwise to a stirring solution of potassium tetrachloridopalladate (0.05 g, 0.16 mmol) in water (5 ml). The resulting yellow solution was stirred for 30 min at 333 K, whereupon the solution was left to evaporate slowly at room temperature. After two weeks, red crystals were isolated [Yield: 30%]. Spectroscopic and TGA data for the title compound are available in the archived CIF.

Refinement top

C bound H atoms were positioned geometrically and constrained using the riding-model approximation [aryl C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C)]. The N—H and O—H hydrogen atoms were located in difference Fourier maps and were refined with distance restraints: N-H = 0.86 (1) for NH3+ H atoms and 0.84 (1) Å for O—H and pyN-H+ H atoms, with Uiso(H) = 1.2Ueq(O,N).

Experimental. Spectroscopic and TGA data for the title compound: IR(KBr, cm-1): 3440, 3211, 3064, 2937, 2888, 1669, 1630, 1509, 1421, 1358, 1294, 999, 832. TGA: Calcd. for HCl: 3.08. Found: 3.26% (303–448 K); Calcd. for PdCl2: 15.49. Found: 15.85% (448–523 K).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell esds are taken into account in the estimation of distances, angles and torsion angles

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
