The title complex, [Cu(C7H2N2O7)(C4H8N2O2)(H2O)], is a mononuclear copper(II) compound. The CuII ion is five-coordinated in a distorted pyramidal geometry by two N atoms from one dimethylglyoxime molecule, two O atoms from one 3,5-dinitro-2-oxidobenzoate ligand and one O atom from a water molecule. Strong hydrogen bonds connect adjacent molecules into a three-dimensional network.

A mixture of dimethylglyoxime (0.116 g, 0.001 mol), 2-hydroxy-3,5-dinitrobenzoic
acid (0.228 g, 0.001 mol) and CuSO4.5H2O (0.250 g, 0.001 mol) in the mole
ratio of 1:1:1 was added to 15 ml me thanol, The mixture was heated at 408 K
for two days in a closed steel chamber with liner. Crystals of (I) were
obtained after reaction mixture cooled to room temperature, untouched in the
air.
The H atoms bonding to C atoms and O atoms of hydroxyl group were located at
calculated positions and refined as riding on their parent atoms with the bond
length fixed to 0.93 Å for C—H and 0.82 Å for O—H, Uiso(H)
being 1.2 times Ueq(C) and Uiso(H) being 1.5 times
Ueq(O); The H atoms bonding to O atoms of water molecules are found
in electron density map and refined with bond lengths fixed to 0.82 Å and
with Uiso(H) = 1.5 times Ueq(O).

Special details top
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. |

As shown in Fig. 1, (I) crystallizes as discrete molecular species. Each copper(II) ion is five-coordinated in a distorted pyramidal geometry by two N atoms from one dimethylglyoxime molecule, two O atoms from one 2-hydroxy-3,5-dinitrobenzoic acid molecule and one O atom from a water molecule. Atoms O6, O7, N3 and N4 located at the base of the pyramid are approximately coplanar with the central Cu1 ion, the maximum deviation from the least-squares plane through all five atoms being 0.081 Å for Cu1, O10 locating at the apex of the pyramid shows a slightly longer bond to Cu1 than O7 and O8. Strong hydrogen bonds are found between adjacent molecules, which including: O(9)—H(9)···O(10)1 (symmetry code 1: -x,-y + 1,-z); O(10)—H(10E)···O(5)2 (symmetry code 2:x,y - 1,z) and O(10)—H(10D)···O(6)1.
