The title complex, [Ba(C
8H
5NO
5)(H
2O)
5]
n, possesses a one-dimensional double-chain structure in which four-membered rings and 18-membered rings are arranged alternately, with the Ba center nine-coordinated by five water molecules and three carboxylate groups from three different ligands. Intermolecular O—H
O hydrogen bonds and strong π–π interactions between pyridine rings extend these chains into a three-dimensional architecture (distance between pairs of adjacent pyridine rings = 3.306 Å; centroid–centroid separation = 3.424 Å).

Alert level G
ABSTM02_ALERT_3_G When printed, the submitted absorption T values will be
replaced by the scaled T values. Since the ratio of scaled T's
is identical to the ratio of reported T values, the scaling
does not imply a change to the absorption corrections used in
the study.

A solution of BaCl2 (0.2497 g, 1 mmol) and H2CCOP (0.2025 g, 1 mmol) was
mixed and stirred at room temperature. Then the mixture was stood at ambient
temperature. By slow evaporation of the solvent, well formed colourless
crystals, suitable for X-ray analysis were obtained after two days.
The H atoms bonded to C atoms were positioned geometrically and allowed to ride
on their parent atoms, with C—H = 0.93 and 0.97 Å, and
Uiso=1.2Ueq (C). The H atoms bonded to O atoms were located
in a difference Fourier maps and refined freely.

Special details top
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. |

5-Carboxyl-1-carboxymethyl-2-oxidopyridinium, as a dicarboxylic acid analogue of betaine (He & Feng, 2007), own versatile coordination behavior to metal ions according to the reported complexes, [Cu(ppbet)4Cl2](ClO4)2]n (Chen et al., 1998), and [Cu(4-OPA)2]n (Zhang et al., 2006). As illustrated in Fig.1, the title complex has a binuclear structure in which the center Ba2+ is nine-coordinated by five water molecules and three carboxylic groups from three different CCOP ligands in monodentate and chelate-bridging bidentate modes, forming a tricapped trigonal prism configuration as [Ba(5—OH-BDC)(H2O)3] (Shuai et al., 2007). It is interesting that two O atoms of formate groups combine the two Ba2+ to form a rhombus while two CCOP ligands adopting the opposite orientations act as bridges to join these rhombuses to be a one-dimensional double chain. It is worth to note intermolecular O—H···O hydrogen bonds are formed to link neighboring chains to form a three-dimensional network. Besides, strong offset face-to-face π-π interactions between pyridinum groups are also involved with the plane-to-plane distance of 3.306 (1) Å and the centroid-centroid distance of 3.424 (3) Å (Fig.2).
