To bis{2–(3,5–dimethyl–1–pyrazolyl)ethyl}amine (1.67 g, 6.4 mmol) was added dropwise a solution of ZnCl2 (0.87 g, 6.4 mmol) in methanol (20 ml). The mixture was stirred for 1 day at room temperature. The solvent was removed and the residue was washed with ether to give white solids. Colorless crystals was obtained from methanol solution. Yield; 1.63 g (64%). Anal. Calculated for C15H27Cl2N5OZn: C, 41.93; H, 6.33; N, 16.30. Found: C, 42.09; H, 6.24; N, 16.46%. 1H NMR (DMSO–d6); δ 5.97 (s, H-Pz), 4.20 (t, CH2-Pz, J=6.0, 5.7 Hz), 3.07 (t, NCH2–, J=5.7, 5.4 Hz), 2.25 (s, CH3-Pz), 2.18 (s, CH3-Pz), where Pz - pyrazolyl.
All H atoms, except H atoms of hydroxy and amine groups, which were refined isotropically, were positioned geometrically and refined using a riding model, with C—H = 0.97Å and Uiso(H) = 1.2Ueq(C) for CH2, and C—H = 0.96Å and Uiso(H) = 1.5Ueq(C) for CH3 H atoms.
The ligand, bis[2–(3,5–dimethylpyrazol–1–yl)ethyl]amine, synthesized (Sorrell & Malachowski, 1983) and its complex of cobalt, copper or zinc was reported (van Berkel et al., 1994). Nickel complex of the ligand was reported as an efficient catalyst for dimerization of enthylene to 1–butene (Ajellal et al., 2006). Aluminium and zinc alkyl complexes bearing the ligand were synthesized and show the activities on polymerization of methyl methacrylate and lactide (Lian et al., 2007). Also palladium complexes containing the ligand were reported (Pañella et al., 2006; Mendoza et al., 2006). In the title complex, the ligand acts as bidentate though it is a potential tridentate. However, the ligand was κ3 bonding mode at zinc from reaction ZnCl2–to–ligand ratio of 2:1 (van Berkel et al., 1994). Herein, we report the crystal structure of Zn(II) complex containing bis[2–(3,5–dimethylpyrazol–1–yl)ethyl]amine as bidentate. The geometry around Zn(II) is an approximately tetrahedron. The dihedral angle between N—Zn—N and Cl—Zn—Cl planes is 89.69 (5)°.
The methanol solvate molecule takes part in the formation of H–bonds system: the hydroxo–group of one is a donor and acceptor in this system - see table of hydrogen–bond geometry.

The ligand, bis[2–(3,5–dimethylpyrazol–1–yl)ethyl]amine, synthesized (Sorrell & Malachowski, 1983) and its complex of cobalt, copper or zinc was reported (van Berkel et al., 1994). Nickel complex of the ligand was reported as an efficient catalyst for dimerization of enthylene to 1–butene (Ajellal et al., 2006). Aluminium and zinc alkyl complexes bearing the ligand were synthesized and show the activities on polymerization of methyl methacrylate and lactide (Lian et al., 2007). Also palladium complexes containing the ligand were reported (Pañella et al., 2006; Mendoza et al., 2006). In the title complex, the ligand acts as bidentate though it is a potential tridentate. However, the ligand was κ3 bonding mode at zinc from reaction ZnCl2–to–ligand ratio of 2:1 (van Berkel et al., 1994). Herein, we report the crystal structure of Zn(II) complex containing bis[2–(3,5–dimethylpyrazol–1–yl)ethyl]amine as bidentate. The geometry around Zn(II) is an approximately tetrahedron. The dihedral angle between N—Zn—N and Cl—Zn—Cl planes is 89.69 (5)°.
The methanol solvate molecule takes part in the formation of H–bonds system: the hydroxo–group of one is a donor and acceptor in this system - see table of hydrogen–bond geometry.
