In the title complex, [Ni(C12H8N2)3](NO3)2·4H2O, the NiII ion is octahedrally coordinated by three bidentate 1,10-phenanthroline ligands, each forming a five-membered chelate ring. In the crystal, O—H⋯O and C—H⋯O hydrogen bonds are present between the complex cations, nitrate anions and water molecules. O—H⋯O hydrogen bonds between the uncoordinated water molecules lead to the formation of a four-membered ring water cluster, with a planar configuration. There were an additional five grossly disordered water molecules in the which were removed by the subroutine SQUEEZE; these were were excluded in the calculation of the molecular weight, etc. π–π stacking interactions between the aromatic rings are also observed [centroid–centroid distances = 3.697 (2), 3.728 (2) and 3.761 (2) Å].

All purchased chemicals were of reagent grade and used without further purification. 4-Amino-5-methyl-2H-1,2,4-triazole-3(4H)-thione (AMTT) was prepared according to the literature procedure (Beyer & Kröger, 1960). AMTT (0.260 g, 2 mmol) and NaOH (0.080 g, 2 mmol) were dissolved in 10 ml deionized water containing 1,10-phenanthroline hydrate (0.396 g, 2 mmol). A water solution (20 ml) of Ni(NO3)2.6H2O (0.290 g, 1 mmol) was added to the above solution. The reaction mixture was placed in a Parr-Teflon lined stainless steel vessel. It was sealed and heated at 403 K for 8 h. Then it was gradually cooled to room temperature and kept at 277 K until pink crystals suitable for X-ray diffraction were obtained (yield: 73% based on 1,10-phenanthroline).
The
of the title compound contains nine water molecules, five of which were disordered and were therefore removed by the command SQUEEZE in PLATON (Spek, 2009). They have been excluded in the calculation of molecular weight, crystal density and Although the H atoms were located from difference Fourier maps, they were included at geometrically idealized positions with O—H = 0.82 and C—H = 0.95 Å and with Uiso(H) = 1.2Ueq(O,C).Metal complexes with polypyridine-containing ligands are of great interest to researchers, and a number of reports have been devoted to this theme. Among polypyridine-containing ligands, 1,10-phenanthroline (1,10-phen) is a very important pyridine derivative, which has attracted much interest in coordination chemistry. Transition metal complexes coordinated with 1,10-phen show excellent photoelectrical capability. The application of a Ni–phenanthroline complex for detection of nucleic acid has also been reported (Qiua et al., 2011). Extensive investigations of small and medium size water cluster structures (H2O)n (n = 2–100) have been reported in recent years (Rodríguez-Cuamatzi et al., 2004). Among the water clusters, the cyclic (H2O)4 is very interesting as it is a simple two-structure model for liquid water. Recently we have reported a tetrameric water cluster ring in the
of a new proton transfer system derived from pyridine-2,6-dicarboxylic acid and 2-amino-4-methylpyridine (Sharif et al., 2010). Here, we present the preparation and the of the title compound and the formation of a tetrameric water cluster with a planar configuration.The title compound is built up of a [Ni(1,10-phen)3]2+ complex cation, two NO3- anions and four uncoordinated water molecules (Fig. 1). In the cation, the NiII ion is octahedrally coordinated by three bidentate 1,10-phen ligands, each forming a five-membered chelate ring. The Ni—N bond distances in the cation are in accord with the values reported for complexes which contain the same ligand (Qiua et al., 2011). The bond angles around the NiII ion involving trans pairs of donor atoms are in a range of 169.85 (10)–172.77 (11)°, while for the cis pairs this range is 79.72 (11)–96.51 (11)°. These values indicate a distortion from an ideal octahedral geometry. The crystal packing of the complex is dominated by numerous hydrogen bonds of the types O—H···O and C—H···O (Fig. 2, Table 1). Hydrogen bonding interactions between the uncoordinated water molecules lead to the formation of a four-membered ring water cluster with a planar configuration (Fig. 3). Moreover, two planar water cluster rings are connected via hydrogen bonds between the nitrate anions and water molecules (Fig. 4). There are also some π–π stacking interactions between the aromatic rings, e.g. Cg1···Cg2i = 3.697 (2), Cg3···Cg4ii = 3.729 (2) and Cg5···Cg5iii = 3.761 (2) Å [Cg1, Cg2, Cg3, Cg4 and Cg5 are the centroids of N2/C7–C10/C12 ring, C4–C7/C11/C12 ring, N4/C19–C22/C24 ring, C16–C19/C23/C24 ring and C28–C31/C35/C36 ring.

Experimental. IR Spectra IR spectra were recorded using FTIR Spectra Bruker Tensor 27 spectrometer (KBr pellets, 4000–400 cm-1). TGA-DTA measurements were performed at heating rate of 10 K min-1 in the temperature range of 298–1273 K, under nitrogen flow of 20 ml min-1 on instrument Perkin Elmer Pyris Diamond Thermogravimetric/Differential Thermal Analyzer. Elemental analyses were performed using a Costech ECS 4010 CHNS analyzer. The FTIR spectrum of the crystals shows broad strong bands at the region 3000–3500 cm-1. In the spectra of the phenanthroline complexes strong bands are observed in three frequency regions, between 700 - 900 cm-1, 1125 - 1250 cm-1, and 1400 - 1650 cm-1 (Schilt & Taylor 1959). In the title complex, these bonds were observed in the regions 721–869 cm -1, 1138- 1225 cm -1 and 1429–1573 in the IR spectra. Thermal Analyses The thermogravimetric analysis curve for compound shows that the weight loss from at 635 K corresponds to the loss of H2O (experimental value 18.76% and calculated value 18.29%). The further decomposition began at 801 K and finished at 803 K indicating the complete removal of organic part of the compound (experimental value 93.34% and calculated value 91.5%). |
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 > 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. |

Metal complexes with polypyridine-containing ligands are of great interest to researchers, and a number of reports have been devoted to this theme. Among polypyridine-containing ligands, 1,10-phenanthroline (1,10-phen) is a very important pyridine derivative, which has attracted much interest in coordination chemistry. Transition metal complexes coordinated with 1,10-phen show excellent photoelectrical capability. The application of a Ni–phenanthroline complex for detection of nucleic acid has also been reported (Qiua et al., 2011). Extensive investigations of small and medium size water cluster structures (H2O)n (n = 2–100) have been reported in recent years (Rodríguez-Cuamatzi et al., 2004). Among the water clusters, the cyclic (H2O)4 is very interesting as it is a simple two-structure model for liquid water. Recently we have reported a tetrameric water cluster ring in the crystal structure of a new proton transfer system derived from pyridine-2,6-dicarboxylic acid and 2-amino-4-methylpyridine (Sharif et al., 2010). Here, we present the preparation and the crystal structure of the title compound and the formation of a tetrameric water cluster with a planar configuration.
The title compound is built up of a [Ni(1,10-phen)3]2+ complex cation, two NO3- anions and four uncoordinated water molecules (Fig. 1). In the cation, the NiII ion is octahedrally coordinated by three bidentate 1,10-phen ligands, each forming a five-membered chelate ring. The Ni—N bond distances in the cation are in accord with the values reported for complexes which contain the same ligand (Qiua et al., 2011). The bond angles around the NiII ion involving trans pairs of donor atoms are in a range of 169.85 (10)–172.77 (11)°, while for the cis pairs this range is 79.72 (11)–96.51 (11)°. These values indicate a distortion from an ideal octahedral geometry. The crystal packing of the complex is dominated by numerous hydrogen bonds of the types O—H···O and C—H···O (Fig. 2, Table 1). Hydrogen bonding interactions between the uncoordinated water molecules lead to the formation of a four-membered ring water cluster with a planar configuration (Fig. 3). Moreover, two planar water cluster rings are connected via hydrogen bonds between the nitrate anions and water molecules (Fig. 4). There are also some π–π stacking interactions between the aromatic rings, e.g. Cg1···Cg2i = 3.697 (2), Cg3···Cg4ii = 3.729 (2) and Cg5···Cg5iii = 3.761 (2) Å [Cg1, Cg2, Cg3, Cg4 and Cg5 are the centroids of N2/C7–C10/C12 ring, C4–C7/C11/C12 ring, N4/C19–C22/C24 ring, C16–C19/C23/C24 ring and C28–C31/C35/C36 ring.
