Crystal Structure of the Organic Metal (DMET)2BF4 with Two Columns along Two Crystallographic Axes

Abstract
The crystal structure of (DMET)2BF4: 5,6-dihydro-2-(4,5-dimethyl-1,3-diselenol-2-ylidene)dithiolo[4,5-b] [1,4]dithiinium tetrafluoroborate (2:1), (C10H10S4Se2)2BF4, is determined. Crystal data: Mr=919.49, triclinic, P\bar1, a=7.032(2), b=7.812(3), c=27.502(11) Å, α=90.87(2), β=90.28(2), γ=106.22(2)°, V=1450.5(15) Å3, Z=2, Dx=2.11 Mg m−3, λ(Mo Kα)=0.71068 Å, μ=5.60 mm−1, F(000)=890, T=297 K, R=0.077 for 4600 reflections. Two crystallographically independent DMET molecules separately form columns along nearly perpendicular directions, and ordered BF4 anions are located between the DMET columns.
