In the title compound, [Na(H2O)4](C15H9N2O2), the Na+ ion is coordinated by six water molecules in an octahedral geometry. The NaO6 octahedra are connected by sharing edges, forming a cationic chain along the b-axis direction. O—H⋯O and O—H⋯N hydrogen bonds link the chains and the 2-(2-pyridyl)quinoline-4-carboxylate anions into a two-dimensional network parallel to (100).

Sodium 2-(2-pyridyl)quinoline-4-carboxylate was prepared by a literature method (Bass et al.,1997). Colourless crystals were obtained by slow evaporation of an aqueous solution of this compound at room temperature.
H atoms bonded C atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93 Å and with Uiso(H) = 1.2Ueq(C). H atoms of water molecules were found from difference Fourier maps and refined as riding atoms, with O—H = 0.85 Å and with Uiso(H) = 1.5Ueq(O).
2-(2-pyridyl)quinoline-4-carboxylic acid is a 2,2'-bipyridyl-like ligand containing a carboxylate substituent, which represents a simple route to some important functionalities. The syntheses of sodium 2-(2-pyridyl)quinoline-4-carboxylate and 2-(2-pyridyl)quinoline-4-carboxylic acid have been reported (Bass et al., 1997; Convers et al., 2004). The structures of 2-(2-pyridyl)-4-methylcarboxyquinoline and its Ru complex have been reported by Farah et al. (2003). Here we present the structure of a sodium salt of 2-(2-pyridyl)quinoline-4-carboxylate in a tetrahydrate form.
The molecular structure of the title compound is shown in Fig. 1. The NaI ion is coordinated by six water molecules in an octahedral geometry. Each coordination octahedron is connected with two adjacent ones by sharing edges, forming a cationic [Na(H2O)4]n chain along the b direction (Fig. 2).
In the
the cationic chains and the organic anions are linked through O–H···O and O–H···N hydrogen bonds into a layer structure (Table 1 and Fig. 3).For the syntheses of sodium 2-(2-pyridyl)quinoline-4-carboxylate and 2-(2-pyridyl)quinoline-4-carboxylic acid, see: Bass et al.

2-(2-pyridyl)quinoline-4-carboxylic acid is a 2,2'-bipyridyl-like ligand containing a carboxylate substituent, which represents a simple route to some important functionalities. The syntheses of sodium 2-(2-pyridyl)quinoline-4-carboxylate and 2-(2-pyridyl)quinoline-4-carboxylic acid have been reported (Bass et al., 1997; Convers et al., 2004). The structures of 2-(2-pyridyl)-4-methylcarboxyquinoline and its Ru complex have been reported by Farah et al. (2003). Here we present the structure of a sodium salt of 2-(2-pyridyl)quinoline-4-carboxylate in a tetrahydrate form.
The molecular structure of the title compound is shown in Fig. 1. The NaI ion is coordinated by six water molecules in an octahedral geometry. Each coordination octahedron is connected with two adjacent ones by sharing edges, forming a cationic [Na(H2O)4]n chain along the b direction (Fig. 2).
In the crystal structure, the cationic chains and the organic anions are linked through O–H···O and O–H···N hydrogen bonds into a layer structure (Table 1 and Fig. 3).
