Coordination compound of samarium(III) with acylhydrazone of N-(2-hydroxyphenyl)iminodiacetic acid and 5-hydroxy-3-methyl-1-phenyl-4-formylpyrazole

Аннотация

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 [Sm₂(Н₃L)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.
