摘要：

Two new coordination compounds of cadmium with HF and XeF2 as ligands have been synthesized. Solid white [Cd(HF)](AsF6)(2) is obtained from an anhydrous HF (aHF) solution of Cd(AsF6)(2). It crystallizes in a monoclinic P2(1)/c space group with a = 9.4687(14) Angstrom, b = 9.2724(11) Angstrom, c = 10.5503(18) Angstrom, beta = 104.887(7)degrees, and Z = 4. The coordination sphere of Cd consists of 7 + 2 fluorine atoms, which are in a capped trigonal-prismatic arrangement. The reaction between Cd(AsF6)(2) and XeF2 in aHF yields a solid white product at room temperature having the composition [Cd(XeF2)(4)](AsF6)(2) after the excess XeF2 and solvent have been removed under dynamic vacuum. [Cd(XeF2)(4)](AsF6)(2) crystallizes in the orthorhombic space group P2(1)2(1)2(1), with a = 8.6482(6) Angstrom, b = 13.5555(11) Angstrom, c = 16.6312(14) Angstrom, and Z = 4. The coordination sphere of Cd consists of eight fluorine atoms, which are at the corners of a trigonal prism with two capped side faces.
