Fe_4S_4[SC(CH_3)_3]_4[(C1H_9)_2,Mr=1193. 23,tetragonal,142d,a = 23. 272(2), c= 13. 080(5) A ,V=7084(3) A3,Z=4,DC=1. 12g·cm-3,UUUU(MoKa) = 10. 8cm-1,F(000) = 2568,R=0. 058 for 1005 observed reflections. The cluster anion contains a cubane-type Fe4S4 core compressed along the 4 axis which is crystallographically imposed. Compared to other salts with different cations ,the core is subject to slight structural distortions in different crystalline environments and crystallographic symmetry of the anion is related to that of the cation.
