Structure and mechanical features of one-dimensional coordination polymer catena-{(μ2-adipato-O,O′)-bis(pyridine-4-aldoxime)-copper(ii)}

Abstract

The mechanical features of catena-{(μ₂-adipato-O,O′)-bis(pyridine-4-aldoxime)-copper(II)} (1) were studied by the nanoindentation technique under different loads. The newly synthesised metal–organic material 1, with a one-dimensional coordination backbone, revealed plastic deformation evidenced by the sliding steps and nanoindentation load–displacement curves and the lack of cracks inside the indentations and in its neighborhood at all load tests. The pattern of the material movement in the crystal volume and its transfer to the surface associated with the shear-induced breakage of weak interlayer forces and the breakage of hydrogen bonds within the H-bonded layer is suggested.
