摘要

Two new quaternary salts, [Hg3Te2][UCl6] and [Hg4As2][UCl6], have been synthesized and their structures determined by single-crystal X-ray diffraction analysis. [Hg3Te2][UCl6] is the product of a reaction involving UCl4, HgCIl(2), and HgTe at 873 K. The compound crystallizes in space group P2(1/c) of the monoclinic system. [Hg4As2][UCl6] results from the reaction of U, Hg2Cl2, and As at 788 K. It crystallizes in space group Pbca of the orthorhornbic system. [Hg3Te2][UCl6] has a two-dimensional framework of (2)(infinity)[Hg3Te22+] layers, whereas [Hg4As2][UCl6] has a three-dimensional framework of (2)(infinity)[Hg3As2] layers interconnected by Hg atoms linearly bonded to As atoms. Both framework structures contain discrete [UCl6](2-) anions between the layers. [Hg3Te2][UCl6] exhibits temperature-independent paramagnetism. The optical absorption spectra of these compounds display f-f transitions. (C) 2008 Elsevier Inc. All rights reserved.
