New Results in the Chemistry of Lanthanoide Complexes. The Crystal Structures of [(C11H21N2)2LnBr] (Ln = Sm, Gd)LnBr3 leads with [(iPr2AIP)Li] (AIP = 2-iPropylamino-4-iPropylimino-2-Pentene) to the mononuclear complex [(iPr2AIP)2LnBr] (Ln = Gd 1, Sm = 2).The structures of 1-2 were characterized by X-ray single crystal structure analysis.1:Space group Cc, Z = 4, a = 1283.3(7) pm, b = 1558.6(8) pm, c = 1330.1(7) pm, β = 90.24(4)°2:Space group Cc, Z = 4, a = 1281.7(2) pm, b = 1562.3(3) pm, c = 1329.8(2) pm, β = 90.09(1)°.The Ln-Ion is coordinated by a Brom-Atom and the four Nitrogen-Atoms of the chelate ligand.
Notes:
LnBr3 reagiert mit [(iPr2AIP)Li] (AIP = 2-iPropylamino-4-iPropylimino-2-Penten) zu dem einkernigen Komplex [(iPr2AIP)2LnBr] (Ln = Gd 1, Sm 2).Der Aufbau von 1-2 konnte durch Kristallstrukturanalyse geklärt werden: 1:Raumgruppe Cc, Z = 4, a = 1283,3(7) pm, b = 1558,6(8) pm, c = 1330,1(7) pm, β = 90,24(4)°.2:Raumgruppe Cc, Z = 4, a = 1281,7(2) pm, b = 1562,3(3) pm, c = 1329,8(2) pm, β = 90,09(1)°. Das Ln-Ion ist durch ein Brom-Atom und die vier Stickstoff-Atome der zwei Chelatliganden fünffach koordiniert.
