| Abstract: | The title complex, bis{µ4-(E)-2-[(5-methoxy-2-oxidobenzylidene)amino]- benzoato}bis{µ2-(E)-2-[(5-methoxy-2-oxidobenzylidene)amino]benzoato}tetracopper( II), [Cu4(C15H11NO4)4] or Cu4 (L) 4, was synthesized by the solvothermal reaction of (E)-2-[(2-hydroxy-5-methoxybenzylidene)amino]benzoic acid (H2L) with copper(II) chloride. It crystallizes in the triclinic system with space group Pi. The tetranuclear structure consists of two fully symmetric dinuclear copper moieties. In the dinuclear copper structural unit, both copper(II) metal centers exhibit a five-coordinate NO4 environment. Of the four coordinating oxygen atoms, two are phenolate oxygen atoms acting as bridges from two different ligands, while the other two oxygen atoms are derived from the carboxyl groups of two distinct ligands, respectively. SHAPE analysis indicates that both copper(II) centers adopt a distorted trigonal--bipyramidal (D3h) geometry. C--H...O hydrogen bonds and C--H...π interactions contribute to the cohesion of the crystal packing. [ABSTRACT FROM AUTHOR] |
