(Received 7 December 2009; accepted 6 January 2010; online 13 January 2010)

In the title coordination polymer, {[Na2(C8H7O3)(H2O)4](C8H7O3)}n, all the non-H atoms except the water O atoms lie on a crystallographic mirror plane. One sodium cation is bonded to four water O atoms and one vanillinate O atom in a distorted square-based pyramidal arrangement; the other Na+ ion is six-coordinated by four water O atoms and two vanillinate O atoms in an irregular geometry. One of the vanillinate anions is directly bonded to two sodium ions, whilst the other only inter­acts with the polymeric network by way of hydrogen bonds. In the crystal, a two-dimensional polymeric array is formed; this is reinforced by O—H⋯O hydrogen bonds, which generate R21(6) and R22(20) loops.

Comment top

The crystal structures of vanillin-I (Velavan et al., 1995), the polymorphic forms of isovanillin (Iwasaki, 1973), o-vanillin (Iwasaki et al., 1976) and other vanillin derivatives (Usman et al., 2002; Li et al., 1999) have been reported. We now report the title compound, (I).

The basic polymeric fragment of (I), with asymmetric unit formula [Na2(H2O)2(C8H7O3)2]n, is illustrated in Fig. 1. The Na+ cations are of two coordination types. In the first of these coordination, the Na1 coordination by four O atoms from two equivalent water molecules (O1, O2, O1iv and O2iv) and the bonded carboxylate O atom from vanillin ligand (O6) (Table 1). In the second coordination, cation Na2 is coordinated by four O atoms from two equivalent water molecules (O1, O2, O1vii and O2vii) and two O atoms from vanillin ligand (O7vi and O8vi) [symmetry codes: (iv) x, 1/2 - y, z; (vi) 3/2 - x, -y, 1/2 + z; (vii) x, -1/2 - y, z]. The vanillin ligand five-membered (O7vi/C11vi/C12vi/O8vi/Na2) chelates to the Na atom through the methoxy and hydroxy groups. Two adjacent Na+ cations are linked together by two H2O bridges to form a four-membered ring with an Na2O2 core. The Na1···Na2 separation is 3.7595 (8) Å. Adjacent Na2O2 binuclear motifs are further joined by the vanillin ligand through carboxyl atoms O6, O7 and O8, to produce a one-dimensional chain along the c axis, with an Na1···Na2ii separation of 9.890Å [symmetry code: (ii) 3/2 - x, 1 - y, z - 1/2]; this compares with the corresponding Na···Na distance of 8.006 (3)Å in the three-dimensional Na-terephthalate polymer [Na2(C8H4O4)] (Kaduk, 2000). These chains are connected by the water O atoms [Na1···Na2v = 3.7595 (8) Å; symmetry code: (v) x, 1 + y, z], generating a two-dimensional layer architecture in the crystallographic bc plane (Fig. 2).

Water atom O1 in the molecule at (x, y, z) acts as a hydrogen-bond donor, via H1B, to atom O8i so forming a C(10)[R22(20)] (Bernstein et al., 1995) chain of rings running parallel to the [0–10] direction and centrosymmetric R22(20) rings centred at (1/2, 1/2+n/2, 1/2) (n = zero or integer). The combination of O1—H1B···O8i and O1ix—H1Bix···O8i hydrogen bonds produce R21(6) ring (Fig. 3). Water atom O2 in the molecule at (x, y, z) acts as a hydrogen-bond donor, via H2A, to atom O4ii, while O1ii acts as donor to O5ii, and in this manner a C22(12) chain running parallel to the [00–1] direction. The combination of O2—H2A···O4ii, O1ii—H1Aii···O5ii and O2ix—H2Aix···O4ii hydrogen bonds produce R21(6) and R22(20) rings (Fig. 4).

Experimental top

Sodium hydroxide (0.66 g, 0.0165 mmol) was dissolved in a mixture of distilled water (10 ml) and ethanol (8 ml). The solution was cooled to room temperature. Half of the mixture of vanillin (1 g, 0.00658 mmol) and acetone (0.19 g, 0.00329 mmol) added to the above solution and stirred at room temperature for 15 minute then the remaining mixture was added and stirred for 2 h under the same conditions. The greenish-yellow precipitate obtained was filtered and recystalized from methanol to yield colourless blocks of (I).

Refinement top

All H atoms bound to C atoms were refined using a riding model, with C—H = 0.93Å and Uiso(H) = 1.2Ueq(C) for aromatic C, and C—H = 0.96Å and Uiso(H) = 1.5Ueq(C) for methyl C atoms. Water H atom was located in difference maps and refined subject to a restraint of O—H = 0.83 (2) Å.

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.
