[Et_4N]_2[Fe_2S_2(Sph)_4]的晶体结构

Crystal Structure of (Et_4N)_2 (Fe_2 S_2 (SPh)_4 )

[Et_4N]_3[Fe_1S_2(Sph)_4]的合成与晶体结构已有报道,本文给出从金刚烷铁硫簇Fe_4(Sph)_(10)作为起始裂解原料,合成得到[Et_4N]_2[Fe_2S_2(Sph)_4]的单斜晶相的结构。从反应后的乙腈溶液得到片状黑色晶体,选取0.3×0.3×0.

The crystal of the title cluster compound (Et4N)2(Fe2S2(SPh)4) is monoclinic, P21/n and with parameter, a=1.2076(1), b=1.329 2(2),c=1.48l 8 (2) nm, β=108.84°(1), Z=2, Dx=1.288 gcm-3. For 26663 independent reflections with I>3σ(1), R=0.053 as measured by EnrafNonius CAD4 diffratometer. The anions of the cluster are centrosymmetric The crystal is of a novel phase which has not been reported so far.
