TThe ligand, 2-(1H-tetrazol-5-yl)pyrimidine (L) was synthesized according to the literature method (Demko & Sharpless, 2001). CuCl2.2H2O (34 mg, 0.2 mmol) and L (60 mg, 0.4 mmol) were dissolved in ammonium hydroxide (20%, 10 ml). The solution was filtered, and then filtrate was allowed to stand for about 10 days. Blue crystals of (I) were isolated in about 30% yield.
H atoms bound to carbon and amine were included in calculated positions and treated in the subsequent refinement as riding atoms, with C—H = 0.93 and N—H = 0.89 Å and Uiso(H) = 1.2 and 1.5 Ueq(C and N), respectively. The H atoms of the water molecules were located in Fourier difference maps and refined with isotropic displacement parameters set at 1.5 times those of the parent O atoms.
The crystal structures of Fe(II) and Co(II) complexes with 5-(pyrimidin-2-yl)tetrazolate ligand have been reported recently (Rodríguez et al., 2005), which feature a two-dimensional square-grid-like network. And, the ligands coordinate to metal atoms through one of the pyrimidinyl nitrogen atoms and the 1- and 3-positon tetrazole nitrogen atoms. The title complex, diamminobis[5-(pyrimidin-2-yl-κN1)tetrazolato-κN1]copper(II) dehydrate (I) performs a mono-nuclear structure (Fig. 1), in which the center CuII atom, located on a normal position, is normally coordinated by two NH3 and two ligand molecules using tetrazole N atoms in 1-position to form a square geometry. Simultaneously, two apical positions in CuII atom form weak coordination (Cu1-N11 = 2.429 (2) and Cu1-N5 = 2.728 (2) Å) with two pyrimidinyl N atoms of two ligands, thus giving a highly distorted octahedral geometry (see Table 1). In addition, a three-dimensional supramolecular framework (Fig. 2) is formed by the intermolecular extensive N-H···O, N-H···N, O-H···N and O-H···O hydrogen-bond interactions between parking water molecules and complex molecules. The hydrogen bond parameters are listed in Table 2.

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. |

The crystal structures of Fe(II) and Co(II) complexes with 5-(pyrimidin-2-yl)tetrazolate ligand have been reported recently (Rodríguez et al., 2005), which feature a two-dimensional square-grid-like network. And, the ligands coordinate to metal atoms through one of the pyrimidinyl nitrogen atoms and the 1- and 3-positon tetrazole nitrogen atoms. The title complex, diamminobis[5-(pyrimidin-2-yl-κN1)tetrazolato-κN1]copper(II) dehydrate (I) performs a mono-nuclear structure (Fig. 1), in which the center CuII atom, located on a normal position, is normally coordinated by two NH3 and two ligand molecules using tetrazole N atoms in 1-position to form a square geometry. Simultaneously, two apical positions in CuII atom form weak coordination (Cu1-N11 = 2.429 (2) and Cu1-N5 = 2.728 (2) Å) with two pyrimidinyl N atoms of two ligands, thus giving a highly distorted octahedral geometry (see Table 1). In addition, a three-dimensional supramolecular framework (Fig. 2) is formed by the intermolecular extensive N-H···O, N-H···N, O-H···N and O-H···O hydrogen-bond interactions between parking water molecules and complex molecules. The hydrogen bond parameters are listed in Table 2.
