Original Kurzfassung:
Single crystals of K1.10Zr2Se6, Rb0.80Zr2Se6 and Cs0.80Zr2Se6 were obtained by reacting powdered mixtures of A2Se (A=K,Rb,Cs), Zr and Se at 850°C. K1.10Zr2Se6 and Rb0.80Zr2Se6 crystallize in space group Immm (Z=2), with a=3.746(3), b=5.354(8), c=21.929(3)Ä and a=3.756(1), b=5.354(8), c=22.81(1)Ä, respectively. Cs0.80Zr2Se6 crystallizes in space group Cmc21 (Z=2), with a=3.747(1), b=24.102(5), c=5.332(2)Ä. The compounds are characterized by complex anionic layers 2_oo[Zr2Se6]x- with intercalated alkali cations. As in ZrSe3, the layers are built from columns of trigonal prisms 1_oo[ZrSe3], connected by additional waist contacts, yielding an eightfold coordination for the Zr atoms. The mean Zr-Se bond lengths correspond to those found in the binary compound. The Se-Se bond lengths are significantly altered, however, indicating a reduction of the Se-Se bond order due to the electron transfer from the alkali metal.
