摘要：

The compounds, Cd(BF4)(TaF6) and Cd(BF4)(BiF6), have been synthesized and characterized by single-crystal X-ray diffraction and Raman spectroscopy. Both isostructural compounds crystallize in the monoclinic P2(1)/c space group with a = 8.2700(6) angstrom, b = 9.3691(6) angstrom, c = 8.8896(7) angstrom, beta = 94.196(3)degrees, V=686.94(9) angstrom(3) for Cd(8F(4))(TaF6) and a = 8.3412(8) angstrom, b = 9.4062(8) angstrom, c = 8.9570(7) angstrom, beta = 93.320(5)degrees, V=701.58(11) angstrom(3) for Cd(BF4)(BiF6). Eight fluorine atoms (4 BF4- + 4 AF(6)(-)) form a surrounding around the cadmium atom in the shape of distorted square antiprism. These compounds are not isostructural with mixed-anion analogues of Ca, Sr, Ba and Pb studied earlier. (C) 2011 Elsevier B.V. All rights reserved.
