Description / Table of Contents:
Preparation and Structure of Li[(Me2NCH2CH2CH2)4Yb]YbCl3 reacts with dimethylaminopropyl lithium in tetrahydrofuran with formation of Li[(Me2NCH2CH2CH2)4Yb]. The X-ray structure determination proves the formation of chelat rings by two of the ligands. The nitrogens of the other two ligands are coordinated to the lithium. The compound crystallizes in the monoclinic space group C2/c with the unit cell parameters a = 27.854(8) Å, b = 9.183(3) Å, c = 20.125(8) Å, β = 96.40° and Z = 8.
Notes:
YbCl3 reagiert mit Me2NCH2CH2CH2Li im Molverhältnis 1 : 4 in Tetrahydrofuran als Lösungsmittel zu Li[(Me2NCH2CH2CH2)4Yb]. Die Röntgenkristallstrukturanalyse zeigt die Ausbildung von Chelatringen durch zwei der Liganden, während die Stickstoffe der anderen beiden Liganden am Lithium koordinativ gebunden sind. Die Verbindung kristallisiert monoklin in der Raumgruppe C2/c mit Z = 8, a = 27,854(8) Å, b = 9,183(3) Å, c = 20,125(8) Å, β = 96,40°.
