A mixture of Cd(NO3)2.4H2O (0.150 g, 0.5 mmol), H2pydc (0.167 g, 1.0 mmol), bpy (0.156 g, 1.0 mmol) and H2O (18 ml) in a 30 ml Teflon-lined autoclave were heated under autogenous pressure at 413 K for five days. After cooling to room temperature, colorless blocks of (I) were obtained. Elemental analysis calculated for C17H13N3O5Cd: C 45.2, H 2.9, N 9.3%; found: C 45.0, H 2.8, N 9.2%.
All the C-bound H atoms were generated geometrically (C—H = 0.93 Å) and refined as riding with Uiso(H) = 1.2Ueq(C). The H atoms of the water molecule were located in a difference Fourier map and refined as riding in their as-found relative positions with free refinement of Uiso. The water H-atom positions reported here should be regarded as tentative.
In the title compound, (I), each CdII atom is six-coordinated in an octahedral geometry (Table 1) by two N atom from the 2,2'-bipyridine (bpy) ligand, and one N atom and three O atoms from three pyridine-2,4-dicarboxylate (pydc2-) dianions (one N,O-bidentate, two O-monodentate) (Fig. 1). The bridging pydc2- species result in a layered, polymeric network propagating in (100). Aromatic π–π interactions between the bpy molecules, with a shortest atom-to-atom distance of 3.721 (4) Å, and probable O—H···O hydrogen bonds (Fig. 2 and Table 2) complete the structure.

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. |

In the title compound, (I), each CdII atom is six-coordinated in an octahedral geometry (Table 1) by two N atom from the 2,2'-bipyridine (bpy) ligand, and one N atom and three O atoms from three pyridine-2,4-dicarboxylate (pydc2-) dianions (one N,O-bidentate, two O-monodentate) (Fig. 1). The bridging pydc2- species result in a layered, polymeric network propagating in (100). Aromatic π–π interactions between the bpy molecules, with a shortest atom-to-atom distance of 3.721 (4) Å, and probable O—H···O hydrogen bonds (Fig. 2 and Table 2) complete the structure.
