Source of material

1-Vinylidazole (0.5 mmol), copper(II) chloride (1 mmol), methanol anhydrous (1.5 mL) and deionized water (0.3 mL) were placed in the heat-resistant glass tube. The mixtures were carefully stirred, and then frozen the tube, finally evacuated and sealed with a gas burner. The tube was placed in the oven at 60° C under the hydro-thermal reaction conditions for 4 days to get good quality white block crystal appeared in the tube wall.

Experimental details

The methyl groups and the NH3 groups were idealized and refined using rigid groups allowed to rotate about the P—C bond (AFIX 137 option of the SHELXL program [2]).

Discussion

The first laboratory synthesis of a copper cluster complex with the Cu4OCl6 structural motif was achieved by Bertrand et al. in 1966 [6]. From that time, many copper clusters of this type were reported [7], [8], [9], [10], [11], [12], and their structural properties and catalytic performance were investigated [13], [14], [15], [16], [17]. Systematic investigation of μ4-oxido cluster formation was reported, helping to understand the formation and stability of the μ4-oxido motif in general [18]. In this study, we chose 1-vinylimidazole and cuprous chloride to synthesis the copper cluster unit of the type “Cu4OCl6”.

The complex has no crystallographic symmetry and contains a tetrahedron of four Cu II atoms coordinating a central μ4-O atom, with the six edges of the tetrahedron bridged by Cl atoms. The copper(II) cations are fourfold coordinated by one O atom, three chloro ligands and one N atom of the ligand. The chloride ligands as the bridges link four copper atoms. The copper(II) and nitrogen distances range from 1.954(6) Å to 1.971(7) Å, respectively. The oxygen atom is associated with four copper atoms with bond lengths from 1.914(5) Å to 1.927(5) Å, which are all within a reasonable range.
