Synthesis and crystal structure of a quinolinolato-complex of dicyclopentylgallim

Abstract

Tricyclopentylgallium reacts with 8-hydroxyquinoline in 1:1 ratio to yield quantitatively bis[dicyclo-pentyl(quinolin-8-olato)gallium] which has been characterized by elemental analysis, IR, ¹H NMR and mass spectrometry. X-Ray diffraction analysis indicated that the compound belongs to the triclinic system, space group P1^–, with a= 10.591(4), b= 12.065(4), c= 13.941(4)Å, α= 81.92(2), β= 87.83(3), γ= 82.55(3)°, Z= 2 (dimers), R= 0.0608 (R′= 0.0871). The molecule contains an oxygen-bridged coplanar Ga₂O₂ four-membered ring.
