摘要:

1,4-bis(3-thianaphthyl)-buta-1,3-diyne, C20S2H10,Mr' 314.43, m.p ' 438 K, monoclinic,P21/c,a' 13.276(1),b' 3.958(1),c' 14.120(3)Å. β ' 92.11(1)Å,V' 741.45 Å3,Z' 2,Dx' 1.408 gm. cm−3, μ ' 3.36cm−1,F(000) ' 324.0, λ(MoK) ' 0.71073 Å,T' 300K, finalRand wRare 0.0303 and 0.0433 respectively using 1022 observations used in structure factor calculation. The monomer structure (withD' 3.664 Å,S1' 3.502 Å and the angle τ1' 62.25˚) does not satisfy the requirements for topochemical polymerisation (Wegner, 1977).
