Cupric nitrate (120.8 mg, 0.5 mmol) was dissolved in water (10 ml). Ammonium hydroxide was added until the solution turned blue. 2-Pyrimidylthioacetic acid (170.2 mg, 1 mmol) was suspended in a small volume of water–ethanol (1:1 v/v); ammonium hydroxide was added until the compound dissolved completely. The two solutions were then mixed. After three weeks, dark-blue crystals were obtained in 65% yield. Analysis found: C 30.41, H 3.83, N 11.82%; calculated for C12H18CuN4O8S2: C 30.20, H 3.91, N 11.78%. IR (cm−1): 3423 (νOH for H2O), 1605, 1384 (νas and νs for COO−), 1551, 1309, 1280.
The water H atoms were located in difference Fourier maps and were refined with distance restraints of O—H = 0.85?(1) Å and H···H = 1.39?(1) Å [Uiso(H) = 0.85 Å2]. The aromatic and aliphatic H atoms were placed at calculated positions (C—H = 0.93 and 0.97 Å) and refined using the riding-model approximation, with Uiso(H) = 1.2Ueq(C).

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. |

Following our studies of complexes of 2-pyrimidylthioacetic acid (Ng et al., 1993; Ma et al., 2004; Hao et al., 2005), we report the structure of the title compound, (I). The four-coordinate Cu atom is in a square coordination geometry that is made up of two O atoms of two carboxylate groups and two O atoms of two water molecules (Fig. 1). Hydrogen bonds connect the molecules and the solvent water molecules into a three-dimensional network structure.
