| Abstract: Reaction of LnCl3(Ln=Pr,Er) with AlCl3 in m-xylene gave rise to the corresponding new complexes η6-(m-Me2C6H4)Ln(AlCl4)3 which were characterized by elemental analysis, IR spectra, MS. The determination of X-ray diffraction for Pr complex indicates the complex has a distorted pentagonal bipyramid geometry with m-xylene in one of apical positions. The complex crystallized in monoclinic space group P21/n with unit cell dimensions a=9.870(3)?，b=16.794(8)?, c=16.025(7)?, β=94.40(3)°, V=2648.51?3, Z=4. The average distance of Pr-C is 2.95(2)?。 |
