• Two new coordination complexes have been synthesized and characterized.
• The magnetic properties of two complexes have been determined in the temperature range of 2.7–300 K.
Two new dissymmetrical Schiff-base copper(II) complexes, [(Cu2L)2(H2O)4]·(CuL)2·4H2O (1) and [Cu2L(dca)]n (2) (H3L = 1-(2-hydroxybenzamido)-2-(2-hydroxy-3-methoxybenzylideneamino)ethane), have been synthesized and characterized by IR, elemental analysis, X-ray crystal diffraction and magnetic properties. Single-crystal structural analysis shows that complex 1 contains a tetranuclear [Cu4L2(H2O)4]2 + cation, two [CuL]− anions and four uncoordinated water molecules. Complex 2 is an infinite two-dimensional network structure in which the tetranuclear [Cu4L2] cations are interlinked by dicyanamide (dca−) bridges in the end-to-end (μ1,5) fashion. The magnetic properties of two complexes have been determined in the temperature range of 2.7–300 K.
