Abstract
The Lanthanum picrate complex with 1, 10-phenanthroline was synthesized, whose chemical formula can be written in [La(pic)(3)(phen)(2)] . CH3CN. The crystal X-ray diffraction analysis shows that crystal belongs to monoclinic with space group P2(1)/a and unit cell parameters: a = 17.072 (4), b = 16.083(4), c = 17.789(4), beta = 106.34(2)degrees V = 4687(4) (3), Z = 4, Dc = 1.735g.cm(3), mu = 10.106cm(-1), F(000) = 2448, R = 0.0589, Rw = 0.0589. The coordination number of La3+ is nine. Acetonitrile, a solvent molecule is not coordinated. Between three Pic ligands, that possesses 2 bidentate forms six-member ring with La. The other is unidentate ligand. As usually, phen is bidentate ligand.
