Abstract

The structure of a samarium(III) complex with acylhydrazone of N-(2-hydroxyphenyl)iminodiacetic acid and 5-hydroxy-3-methyl-1-phenyl-4-formylpyrazole (Н5L) of the composition [Sm23L)3]·С2Н5ОН··10Н2О has been determined by single crystal X-ray diffraction. It has been found that in the dinuclear complex the coordination polyhedra have the geometry of a slightly distorted tri-capped trigonal prism and are linked with three iminodimethylene bridges arranged in a triple helix.
