A Salamo‐type ligand 6,6′‐diethoxy‐2,2′‐[1,1′‐(ethylenedioxydinitrilo)dimethylidyne]diphenol (H 2 L) and its pentacoordinate copper(II) complex [CuL(H 2 O)] were synthesized and structurally characterized. The molecule of H 2 L is located in a crystallographic inversion center and adopts E configuration with respect to the C=N bond. In the complex [CuL(H 2 O)], the Cu II atom has a tetragonally elongated square‐pyramidal configuration with donor atoms N 2 O 2 forming a perfect basal plane. And an infinite 2D layer supramolecular structure is formed through intermolecular C1–H1A ··· O5 and C2–H2A ··· O3 hydrogen bonding interactions.
