Аннотация

A new tetranuclear complex [Cu4(L)4] (1) (H2L = N-(2-hydroxyethyl)-3-metoxysalicylaldimine) has been synthesized and characterized by crystal structure analysis and magnetic susceptibility. Single-crystal X-ray diffraction studies reveal that complex 1 contains three independent Cu4O4 open-cubane cores of 4+2 type (four short and two long Cu⋯Cu distances), where the copper(II) centers are linked by alkoxo-bridges. Each copper(II) ion have a distorted square-pyramidal geometry. Variable-temperature magnetic susceptibility measurements on the tetranuclear complex 1 in the range 2-300 K indicate dominant antiferromagnetic coupling ( J = -108.46) between copper(II) centers.
