The ligand (H3ptc) was synthesized by oxidization of pyridine-2,4,6-trimethyl with potassium permanganate as reported in the literature (Syper et al., 1980). A solution of Ni(ClO4)2.6H2O (0.0731 g, 0.2 mmol), H3ptc (0.0425 g, 0.2 mmol), phen (0.0396 g, 0.2 mmol) in H2O (8.0 ml) wasy sealed in a 23 ml Teflon-lined stainless-steel autoclave, which was heated to 413 K and kept at this temperature for 3 days, then the reactor was slow cooled to room temperature at a rate of 5 K/h, green crystals were collected after filtration.
H atoms bonded to C atoms were placed in their geometrically calculated positions and refined using the riding model, with C–H distances 0.93Å and Uiso(H) = 1.2 Ueq(C). H atoms attached to O atoms were found in a difference Fourier map and then refined using the riding model, with O–H distances fixed at 0.85Å and Uiso(H) values set at 1.2 Ueq(O). The final difference map showed residual electron density close to the Ni-atom which was essentially meaningless.

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. |

The asymmetric unit of the title compound contains a NiII ion, a 1,10-phenanthroline ligand, a 4-carboxypyridine-2,6-dicarboxylate (Hptc2-) anion and a coordinated molecule of water. The Hptc2- anion adopts a η3µ1 coordination mode and chelates the NiII atom through the pyridine N atom and two neighboring carboxylate O atoms. The NiII atoms is six-coordinated by two N atoms from phen, one nitrogen from Hptc2-, two oxygen atoms from Hptc2- and one oxygen from coordinated water, in a octahedral N3O3 environment. The π–π stacking interactions between the parallel phen rings with the interplanar distance of 3.293 (2)Å interlink the [Ni(Hptc)(phen)(H2O)] units to form one-dimensional chains, which further grow into three-dimensional supramolecular construction by hydrogen bonding O—H···O interactions between coordinated water molecules and carboxylate groups.
