Poly[triaqua-μ4-pyridine-3,5-dicarboxyl­ato-barium(II)]

Abstract

The reaction of the proton-transfer compound (pdaH2)(py-3,5-dc)·H2O (pda = propane-1,3-diamine and py-3,5-dcH2 = pyridine-3,5-dicarboxylic acid) with Ba(NO3)2 leads to the formation of the title polymeric compound, [Ba(C7H3NO4)(H2O)3]n. The BaII atom is nine-coordinated by six carboxyl­ate O atoms from the (py-3,5-dc)2− ligands, and three O atoms from the coordinated water mol­ecules. The coordination polyhedron around the BaII atom is best described as tricapped trigonal-prismatic. In the crystal structure, inter­molecular inter­actions, such as X—H(...)O hydrogen bonds (X = O and C) and π–π stacking [centroid–centroid distances between pyridine rings of 3.6191 (13) and 3.6192 (13) Å] play an important role in stabilizing the supramolecular structure.

Comment

Recent interest of our researching group has focused on the synthesis and characterization of novel metal complexes of proton transfer compounds obtained using dipicolinic acid (Aghabozorg et al., 2007). A convenient path to obtain polymeric structures is to use a multifunctional ligand to link metal ions to form an infinite arrangement (Starosta et al., 2002a,b); Dorazco-Gonzalez et al., 2006). The reaction of the proton transfer compound (pdaH2)(py-3,5-dc).H2O [pda = propane-1,3-diamine and py-3,5-dcH2 = pyridine-3,5-dicarboxylic acid (Aghabozorg et al., 2006)] with Ba(NO3)2, in aqueous solution with a 1:2 molar ratio, lead to the formation of the title polymeric compound, (I).

The monomeric units in the polymer (I) consist of one BaII atom, one (py-3,5-dc)2- dianion and three aqua (H2O) ligands. The BaII atom is nine-coordinate with six carboxylate oxygen atoms from the bridging (py-3,5-dc)2- ligands and three oxygen atoms from the coordinated water molecules (Figs. 1 and 2). The summation of bond angles O2W—Ba1—O3ii, O3ii —Ba1—O1 and O2W—Ba1—O1 is 360.94° hence, the Ba1 atom is located in the center of the plane (O1,O2,O3Wii). Atoms O2, O3W and O3i form a triangle, and atoms O1W, O4ii, O4iii form another triangle. So a prism, consisting of six O-atoms and three caps (O2W, O3iii and O1) on the faces around the Ba(II) atom is formed. The coordination polyhedron around the BaII atom is hence, best described as a tricapped trigonal prism (Fig. 3).

In the molecular structure of (I) atoms O1 and O2, from one of the carboxylate groups, have only one Ba—O bond, while atoms O3 and O4 from three neighboring carboxylate groups have two Ba—O bonds. The bond distances between barium and the oxygen atoms are in the range 2.7399 (18)–2.8669 (16) Å.

In the crystal structure of (I) there are several O—H···O hydrogen bonds [in the range 2.730 (2)–2.924 (2) Å], and the pyridine N-atoms have N—H···O hydrogen bonds with neighboring coordinated water molecules [in the range 2.873 (3)–3.284 (3) Å]. C—H···O hydrogen bonds [with D···A distance 3.362 (3) Å], are also present (Table 1). There are π-π stacking interactions between symmetry related pyridine (N1/C1—C5) rings with centroid···centroid distances of 3.6191 (13) and 3.6192 (13) Å (symmetry codes: (i) = x, -y + 3/2, z + 1/2 and x; (ii) = -y + 3/2, z - 1/2, respectively] (Fig.4).

All of these intermolecular interactions play an important role in forming the three dimensional polymeric system and stabilizing the structure.

Experimental

The proton transfer compound (pdaH2)(py-3,5-dc), was prepared by the reaction of pyridine-3,5-dicarboxylic acid [py-3,5-dcH2], with propane-1,3-diamine [pda], (Aghabozorg et al., 2006). Compound (I) was prepared by the reaction between Ba(NO3)2 (292.5 mg, 0.5 mmol in water 25 ml) and the proton transfer compound (pdaH2 )(py-3,5-dc) (241 mg, 1.0 mmol in water 25 ml), in a 1:2 molar ratio. Crystals were obtained by slow evaporation of the solvent at room temperature.

Refinement

The water molecules H-atoms were located in difference Fourier maps and refined with distance O—H restrained to 0.85 (2) Å and Uiso(H) = 1.2Ueq(O). The C-bound H-atoms were included in calculated positions and treated as riding atoms: C—H = 0.93 Å with Uiso(H) = 1.2Ueq(C).

Special details

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.
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.
