Deskripsi

The reaction of the potassium salt of (2,6-diisopropylphenyl)-[6-(2,4,6-triisopropylphenyl)-pyridine-2-yl]-amine (Ap*H) with the equimolar ratio of [ScCl<sub>3</sub>] in tetrahydrofuran (thf) resulted in the mononuclear mono(aminopyridinato) scandium dichloride complex [Ap*ScCl<sub>2</sub>(thf)<sub>2</sub>]. An X-ray analysis showed the title compound to be monomeric. The compound [C<sub>40</sub>H<sub>59</sub>Cl<sub>2</sub>N<sub>2</sub>O<sub>2</sub>Sc] crystallized in the monoclinic space group, <i>P</i>2<sub>1</sub>/<i>n</i>, and possessed the following cell parameters: a  =  12.4441(8) b  =  22.9975(10) c  =  13.9971(8) Å, β  =  92.297(5)°, V  =  4002.5(4) A<sup>3</sup>, and Z  =  4. Hirshfeld analyses show that H…H (91.1%), H…C/C…H (5.0%), and H…Cl/Cl…H (3.9%) are the contributing interactions in the solid-state structure. The compound was further characterized by NMR spectroscopy, and its purity was confirmed by elemental analysis.
