In the title polymer, [Cd(C5H3N2O2)(NO3)(H2O)]n, the CdII atom is seven-coordinate in a distorted capped octa­hedral geometry by two N atoms of two different pyrimidine dicarboxyl­ate (pmc) ligands, three O atoms from three separate pmc ligands, and two O atoms of disordered nitrate anions or water mol­ecules. The CdII atoms are bridged by the pmc ligands in a chelating/bridging bis-bidentate and chelating bidentate mode, forming sheets parallel to (20-1). The sheets are further linked into a three-dimensional supra­molecular network via classical O—H⋯O hydrogen bonds involving the nitrate anions and coordinating water mol­ecules. Intra­molecular O—H⋯O hydrogen bonding is also observed. The non-coordinating nitrate O atoms are disordered over two sets of sites with occupancies of 0.57 (7) and 0.43 (7).

Comment top

Pyrimidine-2-carboxylate (pmc) ligand exhibits a N2O2 donor set with a charge of -1. Due it is rigidity and directionality, the pmc ligand has been used in the construction of coordination polymers exhibiting permanent microporosity for gas storage (Sava et al., 2008) and antiferromagnetism with TN = 21 K (Rodríguez-Diéguez et al., 2007). Here, we report the crystal structure of a novel cadmium(II) coordination polymer containing the pmc ligand, [Cd(C5H3N2O2)(H2O)(NO3)] (I). The pmc ligand was unexpectedly hydrolyzed in situ from the 1,4–dihydro–3,6–bis(2'–pyrimidyl)–1,2,4,5–tetrazine (H2bmtz) ligand during the crystallization process.

The immediate coordination environment about the cadmium atom in I is shown in Fig. 1 revealing that the Cd(II) atom is heptacoordinate in a distorted capped octahedral geometry constructed by two N and two O atoms from two different pcm ligands, one O atom from a third pcm ligand, and two O atoms of disordered nitrate anions or water molecules. The Cd—N and Cd—O bond distances (Table 1) agree with those found in other N,O–chelate Cd(II) complexes (Sava et al., 2008; Zhang et al., 2008). Each Cd(II) is connected to four other Cd atoms through three pmc ligands generating two dimensional sheets parallel to (201), Fig. 2. Within the sheets, the Cd···Cd distances through the µ2–carboxylate bridge and the Cd···Cd distances across the pmc ligands are 3.9714 (4) and 6.2427 (3) Å, respectively. The sheets are stabilized by inversion-related pairs of intermolecular O—H···O hydrogen bonds between the coordinated water and nitrate molecules (Table 2). There are, however, no π–π interactions between adjacent pyrimidine rings within the sheets. The distance between Cg to Cg of the pyrimidine rings of the pmc ligands is 4.114 (3) Å, which is out the range (3.3–3.8 Å) considered for significant π–π interactions (Janiak, 2000). Further intermolecular O—H···O hydrogen bonds involving the nitrate anions and coordinated water molecules (Table 2) link the sheets into a three dimensional supramolecular network, Fig. 3.

Experimental top

Cadmium nitrate tetrahydrate (30 mg, 0.10 mmol) was dissolved in 2 ml acetonitrile in a glass vial. A solution of 1,4-dihydro-3,6-bis(2'-pyrimidyl)-1,2,4,5-tetrazine (10 mg, 0.04 mmol) in 2 ml dichloromethane was carefully layered on top of the acetonitrile solution. The reaction mixture was allowed to stand undisturbed at room temperature. Pale-green plate-like crystals of I were obtained after three months (yield ca. 7% based on Cd source).

Refinement top

The carbon-bound hydrogen atoms were placed in geometrically idealized positions and constrained to ride on their parent atom positions with C—H distances of 0.93 Å and with Uiso(H) = 1.2Ueq(C) for the aromatic H atoms. The hydrogen atoms attached to oxygen atoms of the water molecules were located in a difference Fourier map and refined as riding in their as-found positions with a DFIX restraint of O—H distance at 0.900±0.001 Å, with Uiso(H) = 1.2Ueq(O). The nitrate anion was shown to be disordered over two sites in a 0.57 (7) and 0.43 (7) ratio. The N—O bond lengths were restrained to 1.25±0.01 Å and the O···O distances to 2.17±0.01 Å. The highest peak in the final electron density difference map is located 0.85 Å from Cd1 atom.

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.
