The 3Na2(C11H8N2O3)4(CH4O)]n, consists of two NaI atoms, three CuII atoms, four 5-(4-methoxyphenyl)pyrazole-3-carboxylate ligands and one methanol molecule. The central CuII atom is coordinated by four N atoms from four pyrazole-3-carboxylate ligands, forming a distorted tetrahedral (CuN4) geometry, while each of the other two CuII atoms is coordinated by two O atoms and two N atoms from the two ligands, forming a slightly distorted square-planar (CuN2O2) geometry. Each of the two NaI atoms is coordinated by five O atoms, forming a distorted octahedral geometry; four O atoms are from the carboxylate groups of the three ligands and the remaining O atom is from the methoxy group of the ligand or from the methanol molecule.

5-(4-Methoxyphenyl)-1H-pyrazole-3-carboxylic acid (0.044 g, 0.2 mmol) was added to a solution of copper acetate dihydrate (0.040 g, 0.2 mmol) in methanol (15 ml), the resulting mixture was treated with a solution of NaOH until the pH value come rise to be about 8. The mixture was then stirred continuously for 7 h, and the filtrate was kept in conical flask for about 40 days and some brown block crystals were obtained from the solution, dried in vacuum. Yield: 37.6%. Crystal of the title compound suitable for single-crystal X-ray diffraction was selected directly from the sample as prepared.
All H atoms were positioned geometrically and refined using a riding model, with C—H = 0.93 Å for aromatic H atoms, 0.96 Å for methyl H atoms, respectively, and with Uiso(H) = 1.2Ueq(C) for aromatic and methylene H atoms, Uiso(H) = 1.5Ueq(C) for methyl H atoms.
Due to their significant interest, the synthesis, structure and properties of copper pyrazolates (Trofimenko, 1972; Omary et al., 2003; Fujisawa et al., 2004), especially, trinuclear copper complexes (Mezei et al., 2004; Spiccia et al., 1997), have been extensively studied. For this kind of complexes have been found to exhibit a variety of structures ranging from polymers to trimers. Besides, the trinuclear copper complexes are known to be important models for the study of testing magnetic exchange models as well as spinfrustration. As a part of our ongoing study of different environment where the reaction of copper (II) with 5-aryl-1H-pyrazole-3-carboxylic acid (Zhou et al., 2007). In this work, we describe the reaction of copper (II) with the ligand (5-(4-methoxyphenyl)-1H-pyrazole-3-carboxylic acid) in the presence of NaOH, which was used to deprotonate the ligand so as to improve the coordination capability of the ligand.
As can be seen from the
in Fig.1, the unit of the crystal is mainly made up of the sodium cations part and the anion part. The anion consists of three Cu(II) ions and four ligands. The X-ray analysis reveals that not all the coordination modes of copper(II) ions are the same. The central copper(II), Cu1, is coordinated by four N atoms, which are from four ligands, forming a distorted tetrahedral (CuN4) geometry. On the other hand, the Cu2 and Cu3 have the similar coordination modes, coordinated by two O atoms and two N atoms of two ligands, respectively, forming a slightly distorted square planar (CuN2O2) geometry. In the cations, the coordination modes of the two sodium ions are similar in general, however, Na1 is coordinated by five O atoms, four of which are from three ligands, the other from the methoxy group of the 5-position substituted group of the pyrazole; Na2 is coordinated by five O atoms too, four of which are from three ligands, but the other from the methanol molecule. The cations connect the anions each other, forming a three-dimensional structure in the crystal (Fig. 2).For related literature, see: Fujisawa et al. (2004); Mezei et al. (2004); Omary et al.

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. |

Due to their significant interest, the synthesis, structure and properties of copper pyrazolates (Trofimenko, 1972; Omary et al., 2003; Fujisawa et al., 2004), especially, trinuclear copper complexes (Mezei et al., 2004; Spiccia et al., 1997), have been extensively studied. For this kind of complexes have been found to exhibit a variety of structures ranging from polymers to trimers. Besides, the trinuclear copper complexes are known to be important models for the study of testing magnetic exchange models as well as spinfrustration. As a part of our ongoing study of different environment where the reaction of copper (II) with 5-aryl-1H-pyrazole-3-carboxylic acid (Zhou et al., 2007). In this work, we describe the reaction of copper (II) with the ligand (5-(4-methoxyphenyl)-1H-pyrazole-3-carboxylic acid) in the presence of NaOH, which was used to deprotonate the ligand so as to improve the coordination capability of the ligand.
As can be seen from the crystal structure in Fig.1, the unit of the crystal is mainly made up of the sodium cations part and the anion part. The anion consists of three Cu(II) ions and four ligands. The X-ray analysis reveals that not all the coordination modes of copper(II) ions are the same. The central copper(II), Cu1, is coordinated by four N atoms, which are from four ligands, forming a distorted tetrahedral (CuN4) geometry. On the other hand, the Cu2 and Cu3 have the similar coordination modes, coordinated by two O atoms and two N atoms of two ligands, respectively, forming a slightly distorted square planar (CuN2O2) geometry. In the cations, the coordination modes of the two sodium ions are similar in general, however, Na1 is coordinated by five O atoms, four of which are from three ligands, the other from the methoxy group of the 5-position substituted group of the pyrazole; Na2 is coordinated by five O atoms too, four of which are from three ligands, but the other from the methanol molecule. The cations connect the anions each other, forming a three-dimensional structure in the crystal (Fig. 2).
