Synthesis and crystal structure of a quinolinolato-complex of dicyclopentylgallim
摘要:
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, H-1 NMR and mass spectrometry. X-Ray diffraction analysis indicated that the compound belongs to the triclinic system, space group P1BAR, with a = 10.591(4), b = 12.065(4), c = 13.941(4) angstrom, alpha = 81.92(2), beta = 87.83(3), gamma = 82.55(3)-degrees, Z = 2 (dimers), R = 0.0608 (R' = 0.0871 ). The molecule contains an oxygen-bridged coplanar Ga2O2 four-membered ring.
