The title complex, bis[2-(1H-imidazol-4-yl)ethanamine]disaccharinatonickel(II), [Ni(C7H4NO3S)2(C5H9N3)2], has an octahedral coordination around the nickel(II) ion, and the Ni atom lies on a center of symmetry. The histamine ligands and sulfonyl group of the saccharinate ligands show disorder, and the two conformations (A and B, with almost equal occupancy) are inversion isomers. The molecular packing is stabilized by intra- and intermolecular hydrogen bonds between imidazole N atoms and sulfonyl O atoms. In the extended stucture, intermolecular N-H
O hydogen bonds constitute a chain structure parallel to the direction [110].
A solution of histamine (2 mmol, 0.222 g) in water (10 ml) was added dropwise upon stirring to the mixture of sodium saccharinate (2 mmol, 0.412 g) and NiCl2·H2O (1 mmol, 0.238 g) in distilled water (30 ml). The solution was heated to 60°C in a temperature-controlled bath and stirred for 8 h at 60°C and then filtered. The blue filtrates were left about two weaks at room temperature, and then the blue crystals of title complex suitable for x-ray diffraction analyses were collected.
The sulfonyl group of sacharinate ligand and the histamine ligand show disorder, which is modelled as two different orientations (C8A—C11A, C8B—C11B; S1A—S1B; O1A—O2A, O1B—O2B) with occupancy factors of 0.507 (8) and 0. 493 (8). All H atoms except those bonded to N4 atom were placed in geometricaly idealized positions, [N—H = 0.90 Å; C—H = 0.93 − 0.97 Å], and refined as riding atoms.

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 > 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. |

The title compound, (I), is composed of discrete [C24H26N8NiO6S2] molecules. As shown in Figure 1, the nickel atom lies on a center of symmetry and is coordinated by four N atoms of two bidentate histamine ligands and monodentate saccharinato ligands. The geometry around the Ni(II) ion is an elongated octahedron. Related bond distances and angles are given in Table 1. The equatorial plane (N2/N3/N2i/N3i) is formed by N atoms of histamine ligands while the axial positions are occupied by saccharinate N atoms. It is observed that the apical Ni–N bond distance is longer than the basal Ni–N bond distances. The intraligand bond distances are comparable to those observed in the complex [C24H26N8CuO6S2] (Bulut et al., 2007).
Histamine ligand and sulfonyl group of saccharinato ligand show disorder, which is modelled as two different orientations with the occupancy factors of 0.493 (8) for conformer A and 0.507 (8) for conformer B. Both conformers, being inversion isomers, have similiar bond angles and distances. These values are also in good agreement with those found in [C24H26N8CuO6S2] (Bulut et al., 2007).
The molecular packing is stabilized by intra- and inter-molecular hydrogen bonds (Table 2). The neutral complexes are linked by N—H···O hydrogen bonding interactions between the imidazole N atoms of histamine and sacchatinate sulfonyl O atoms. As is seen from Figure 2, imidazol atom N4 acts as a donor atom, via H4a, to atom O2a, producing a chain C(8) (Bernstein et al., 1995) running parallel to the direction [110] and centrosymmetric [R22(16)] rings centered at (n+1/2, n+1/2, 0) (n=zero or integer).
