Bis­[2-(phenethyl­imino­methyl)­phenolato-κ²N,O]copper(II)

The title compound, [Cu(C₁₅H₁₄NO)₂], adopts a stepped conformation and displays a square-planar trans-[CuN₂O₂] coordination geometry. The asymmetric unit contains two independent half mol­ecules and each Cu atom is located on a center of symmetry. For one mol­ecule, the Cu—N and Cu—O bond distances are 2.013 (2) and 1.893 (2) Å, respectively, while for the other mol­ecule, these distances are 2.008 (2) and 1.896 (2) Å. The extended conformation of the phenethyl­imine pendant groups results in crystal packing formed by weakly aggregated planar mol­ecules.

Special details

Refinement. Refinement using reflections with F² > 0.0 σ(F²). The weighted R-factor (wR), goodness of fit (S) and R-factor (gt) are based on F, with F set to zero for negative F. The threshold expression of F² > 2.0 σ(F²) is used only for calculating R-factor (gt).
