A mixture of isonicotinic acid (0.0615 g), Sm(NO3)3.6H2O (0.114 g), AgNO3 (0.051 g, 0.3mmol), oxalic acid dihydrate (0.037 g, 0.3mmol) and water (10 ml) was heated at 430 K for 72 h in a 23 ml Teflon-lined stainless-steel autoclave and then cooled to room temperature at a rate of 278° per hour. Colourless prismatic crystals were collected, washed with water three times and dried in air.
All H atoms were placed at calculated positions and were treated as riding on the parent C atoms with C—H = 0.93 |%A and O—H = 0.86 Å, and with Uiso(H) = 1.2 or 1.5 Ueq(C, O). The H atoms of the water molecule (O1W) were found from the difference Fourier maps and fixed using AFIX within SHELXL97 (Sheldrick, 2008).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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. |

Microporous metal-organic frameworks (MMOFs) are of great current interest in view of their fascinating structural topologies and potential applications, e.g. in small molecule gas storage, separation and catalysis (Sun et al., 2006; Wu et al., 2005; Cho et al., 2006). However, most of the works have so far focused on the assembly of 3d block metals with organic ligands as linkers and many 3d-4f heterometallic MOFs have also been reported. However, the 4d-4f heterometallic compounds based on the isonicotinic acid (ina) ligand have received less attention (Gu et al., 2006; Gu et al., 2007; Ma et al., 2009; Cai et al., 2009). The preparation of 4d-4f MMOFs has certain difficulties because of the high coordination number of 4f block metals, which frequently leads to interpenetration and consequently results in a decrease of the pore size or the MMOF may even become nonporous. Therefore the selection of the organic ligands becomes a key point in the preparation of 4d-4f heterometallic MMOFs. Herein, we report the structure of the title compound {[SmAg(C6H4NO2)2(C2O4)].H2O}n (I) involving SmIII, AgI and the organic nicotinate and oxalate ligands, which has a microporous structure.
In the title compound (Fig. 1), the asymmetric unit contains one SmIII ion, one AgI ion, two unique isonicotinate (ina) ligands, two half oxalate (ox) ligands [one on an inversion centre (associated with O5 and O6), the other on a two-fold axis (associated with O7 and O8)] and one uncoordinated water molecule of solvation (O1W). The central SmIII ion is nine-coordinate with four O-donor atoms from separate bidentate bridging ox ligands and five O-donors from the two ina ligands (both bidentate) [Sm—O bond length range, 2.389 (4)–2.791 (4) Å], giving a distorted monocapped square antiprismatic stereochemistry. The three-coordinate AgIion is surrounded by two N-donor atoms from the two ina ligands [Ag–N, 2.181 (6), 2.185 (5) Å] and one O atom from a bridging oxalate ligand giving a T-shaped coordination geometry. The Ag—O bond [2.620 (4) Å] is long but this and the N—Ag—N angle [154.3 (2)°] are similar to those found in other AgI complexes having T-shaped configurations. The oxalate ligands bridge Sm centers to form a two-dimensional lanthanide-oxalate layered network. In the packing arrangement of the title compound, 'linear' N–Ag–N linkages play an important role in connecting the adjacent two-dimensional layers, forming a three-dimensional pillar-layered coordination polymer with microporous structures. Topological studies performed using the software package TOPOS 4.0 (Blatov & Shevchenko, 2006; Blatov et al., 2000) reveal that this topology is a unique five-nodal (3,4,6)-connected net. The water molecule of solvation also gives O–H···O hydrogen-bonding interactions with oxalate and isonicotinate O acceptors (Table 1).
