The title complex, tetraaqua{1-[(1H-benzotriazol-1-yl)methyl]-1H-1,2,4-triazole-κN4}(sulfato-κO)copper(II) sesquihydrate, [Cu(SO4)(C9H8N6)(H2O)4]·1.5H2O, is composed of one copper atom, one 1-[(2H-benzotriazol-1-yl)methyl]-1-H-1,2,4-triazole (bmt) ligand, one sulfate ligand, four coordinated water molecules and one and a half uncoordinated water molecules. The CuII atom is six-coordinated by one N atom from a bmt ligand and five O atoms from the monodentate sulfate ligand and four water molecules in a distorted octahedral geometry. In the crystal, adjacent molecules are linked through O—H⋯O and O—H⋯N hydrogen bonds involving the sulfate anion and the coordinated and uncoordinated water molecules into a three-dimensional network.

The ligand 1-((benzotriazol-1-yl)methyl)-1-H-1,2,4-triazole (0.1 mmol) in methanol (4 ml) was added dropwise to an aqueous solution (2 ml) of copper sulfate (0.1 mmol). The resulting solution was allowed to stand at room temperature. After three weeks blue crystals with good quality were obtained from the filtrate and dried in air.
H atoms are positioned geometrically and refined as riding atoms, with C-H = 0.93 (aromatic) and 0.97 (CH2) Å and O-H = 0.85 Å, and with Uiso(H) = 1.2 Ueq(C,O).

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. |

Triazole and benzotriazole derivatives have been widely used in the construction of complexes since they can act as polydentate ligands and function as bridging ligands (Aromia et al., 2011; Meng et al., 2009). Moreover, CuII complexes have attracted more and more attention owing to their intrinsic esthetic appeal and potential applications in various fields (Zhou et al., 2007; Brown et al., 2009). In this work, through the reaction of 1-((benzotriazol-1-yl)methyl)-1-H-1,2,4-triazole (bmt) with copper sulfate at room temperature, we obtained the title complex [Cu(bmt) (SO4) (H2O)4] (H2O)1.5, which is reported here. As shown in Figure 1, each CuII ion is located in a slightly distorted octahedral environment and is coordinated to one nitrogen atom from the bmt ligand, five oxygen atoms from four water molecules and one monodentate sulfate. Atoms O1, O2, O4, N1 and Cu1 are nearly co-planar (the mean deviation from the plane is 0.0203 Å). The apical Cu1—O3 and Cu1—O5 bond lengths (2.331 (2) and 2.465 Å) are considerably longer than the equatorial ones (1.974 (2)- 2.002 (2) Å) due to the Jahn-Teller effect. Intramolecular O—H···O hydrogen bonds stabilize the molecular configuration and O—H···O, O—H···N hydrogen bonds between adjacent molecules consolidate the crystal packing.
