Title: Synthesis and crystal structure of EuBi{sub 2}

The new hypervalent binary phase EuBi{sub 2} was obtained from high temperature solid-state reactions of the pure metal elements in welded Ta tubes under argon atmosphere. Its structure was established by single-crystal X-ray diffraction. The title compound crystallizes in the tetragonal space group I4{sub 1}/amd (No. 141) with cell parameters of a=4.726(1),c=34.221(9)A,V=764.3(3)A3, and Z=8. The structure of EuBi{sub 2} is isotypic with HfGa{sub 2} and features 1D Bi{sup -} zigzag anionic chains along both a- and b-axes and 2D Bi{sup -} square sheets normal to c-axis. It can be formulated as Eu{sup 2+}(Bi){sub chain}{sup -}(Bi){sub square}{sup -}.
