Abstract: The salicylaldehyde semicarbazonate anion O,N,O-chelates to the Cu atom in the title compound, bis[-2-(semicarbazonomethyl)phenolato]-1³O³,N¹,O:2O;1O:2³O³,N¹,O-bis[(formato-O)copper(II)] [Cu₂(C₈H₈N₃O₂)₂(CHO₂)₂], the N and O atoms occupying three sites of the square-planar environment around it. The fourth site is occupied by the negatively charged O atom of the formate anion. Two molecules are bridged through the phenoxy O atom across a center of symmetry to give a dinuclear compound, so that the Cu atom exists in a square-pyramidal geometry [CuO_phenoxy = 2.546 (1) Å in the apical position]. Hydrogen bonds link the dinuclear molecules into a three-dimensional network architecture.
