In the title compound, [Ba(C₈H₅NO₄)(H₂O)]_n, the Ba^II ion is eight-coordinated by six O atoms and one N atom from five 5-aminoisophthalate ligands and one water molecule in a distorted dodecahedral geometry. The Ba^II ions are connected via the ligands into a layer parallel to (011). The layers are linked by N—H⋯O hydrogen bonds. The coordinated water molecule is involved in intralayer O—H⋯O hydrogen bonds.

Comment top

The increasingly rapid development of metal coordination polymers over the past two decades has attracted considerable attention due to their structural diversity and important applications (Kitagawa et al., 2004). 5-Aminoisophthalic acid has been successively reported as sodium (Zeng et al., 2007), zinc (Kongshaug & Fjellvåg, 2006) and magnesium complexes (Wu & Lin, 2010). In our continuous investigations in metal coordination polymers, we report here the structure of a new Ba(II) coordination polymer based on the 5-aminoisophthalate ligand.

In the title compound (Fig. 1), the Ba^II ion is eight-coordinated by six O atoms and one N atom from five 5-aminoisophthalate ligands and one water molecule in a distorted dodecahedral geometry. The Ba—O distances range from 2.6808 (16) to 2.8813 (17) Å. The Ba—N distance is 2.918 (2) Å. The BaO₇N dodecahedra are connected via the anionic ligands into a layer parallel to ( 0 1 1). The coordinated water molecule is involved in intralayer O—H···O hydrogen bonds (Table 1 , Fig. 2). These layers are linked by interlayer N—H···O hydrogen bonds (Fig. 3).

Experimental top

Solvothermal reactions were carried out at 423 K for 2 d in a Teflon-lined acid digestion bomb with an internal volume of 23 ml followed by slow cooling at 6 K h^-1 to room temperature. A single-phase product consisting of transparent crystals was obtained from a mixture of 5-aminoisophthalic acid (C₈H₇NO₄, 0.145 g, 0.8 mmol), Ba(NO₃)₂.4H₂O (0.105 g, 0.2 mmol), methanol (5.0 ml) and H₂O (1.0 ml).
