主　　题：Ta Te A NEW TYPE OF CHAIN COMPOUND,STRUCTURE OF TA4 TE2 

摘      要：Ta_4(Te_2)_4Te_4I,Mr=2381.90,Monoclinic,C2/c,a=21.987(2),b=6.153(2),c= 19.936(3),β=122.42(14),V=2276.7 ~3,z=4,Dm=6.8(5)g/cm^3,Dc=6.95g/cm^3,λ(Mok)= 0.71073,μ=354.0cm^(-1),F(000)=3876,T=296(1)k,R=5.3%,Rw=6.8%,for 1118 unique observed reflections(13σ(Ⅰ)).The structure is composed of [Ta_4(Te_2)_4Te_4I]_∞~ chains,which are formed by the four-nuclear butterfly cluster units Ta_4(Te_2)_4Te_4 with the Ⅰ atoms as the bridging atoms between different cluster units.
