The title mononuclear NiII complex, [Ni(C11H11N2O5)2(C2H8N2)2], is built up by inversion symmetry associated with the central Ni atom. The ethylenediamine ligands are non-planar. The r.m.s. deviation from the mean plane of the five-membered Ni–ethylamine chelate ring plane is 0.1945 Å. In the complex molecules are linked to each other via N—H⋯O and O—-H⋯O hydrogen bonding through translation symmetry along the b and c axes, resulting in an extended supramolecular network.

To a stirred solution of N-benzyl-N'-(ethanolamine)oxamide (2mmol, 0.496g) in methanol(20ml), sodium ethoxide (0.136 g, 2mmol) and Ni(ClO4)2.6H2O (0.366g, 1mmol) was added. 10 min later, ethylenediamine (0.056 g, 1mmol) was added. The mixture was then stirred and heated at 323K for 6 h, then filtered. By slow evaporation of the filtrate, green crystals suitable for X-ray investigation were obtained after three weeks. Yield, 56%, analysis, calculated for C26H38N8O10Ni: C 45.83, H, 5.62; N 16.45%; found: C 45.81, H 5.68, N, 16.49%.
H atoms were positioned geometrically [0.93 (CH), 0.97 (CH2), 0.86 (NH), 0.90 (NH2) and 0.82 (OH)Å] and constrained to ride on their parent atoms with Uiso(H) =1.2(1.5 for hydroxy O) Ueq(C/N).
Oxamido compounds and their complexes have been investigated extensively (Ruiz et al., 1999) by virtue of their bioactivities and the versatile bridging function (Ojima & Nonoyama, 1988). We selected 2-[N'-(ethanolamine)-oxamido]benzoate as a bridging ligand and ethylenediamine as another ligand to synthesize a new mononuclear nickel(II) compound, (I).
The title compound, (Fig. 1), is a mononuclear nickel(II) complex containing a total of 45 non-H atoms. The molecule is centrosymmetric with the central core Ni atom and the structure is similar to those seen previously in resemble compounds (Icbudak et al., 2003). The Ni1 atom is in a trans-octahedral coordination geometry. Here, O1 and O1ii [symmetry code: -x, -y + 1, -z + 1] are in axial positions [O1—Ni1—O1ii =180.0°] and the N atoms of the two ethylenediamine groups are in equatorial positions. The sum of the equatorial N—Ni—N angles is 360.0°, indicating a coplanarity for these atoms. The planar oxamide group (r.m.s. deviation 0.0056 Å) displays a
and makes a dihedral angle of 4.2 (8)° with the benzene ring (r.m.s. deviation 0.0031 Å), whereas the ethanol plane is rotated out of the oxamide group by a dihedral angle of 73.4 (8)°.In the
the mononuclear molecules are linked by the N-H···O and O-H···O intermolecular hydrogen bonds into a two-dimensonal network extending parallel to the bc plane (Figure 2).For background to oxamido compounds, see: Ruiz et al. (1999); Ojima & Nonoyama (1988). For related structures, see: Icbudak et al. (2003).

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 > 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. |

Oxamido compounds and their complexes have been investigated extensively (Ruiz et al., 1999) by virtue of their bioactivities and the versatile bridging function (Ojima & Nonoyama, 1988). We selected 2-[N'-(ethanolamine)-oxamido]benzoate as a bridging ligand and ethylenediamine as another ligand to synthesize a new mononuclear nickel(II) compound, (I).
The title compound, (Fig. 1), is a mononuclear nickel(II) complex containing a total of 45 non-H atoms. The molecule is centrosymmetric with the central core Ni atom and the structure is similar to those seen previously in resemble compounds (Icbudak et al., 2003). The Ni1 atom is in a trans-octahedral coordination geometry. Here, O1 and O1ii [symmetry code: -x, -y + 1, -z + 1] are in axial positions [O1—Ni1—O1ii =180.0°] and the N atoms of the two ethylenediamine groups are in equatorial positions. The sum of the equatorial N—Ni—N angles is 360.0°, indicating a coplanarity for these atoms. The planar oxamide group (r.m.s. deviation 0.0056 Å) displays a transoid conformation and makes a dihedral angle of 4.2 (8)° with the benzene ring (r.m.s. deviation 0.0031 Å), whereas the ethanol plane is rotated out of the oxamide group by a dihedral angle of 73.4 (8)°.
In the crystal structure, the mononuclear molecules are linked by the N-H···O and O-H···O intermolecular hydrogen bonds into a two-dimensonal network extending parallel to the bc plane (Figure 2).
