Abstract:
The reaction of Se-4[MoOCl4] and Te-4[MoOCl4] with SOCl2 as solvent at 150 degrees C and 80 degrees C yields [SeCl3][MoOCl4] and [TeCl3][MoOCl4] respectively within 3 to 6 days as yellow-brown, moisture-sensitive crystals. [TeCl3][MoOCl4] was obtained in the already known monoclinic form, while beta-[SeCl3][MoOCl4] crystallizes in a new polymorphic triclinic form (, Z=2, a=752.7(2), b=812.8(2), c=956.9(3)pm, alpha=92.55(3)degrees, beta=111.63(2)degrees, gamma=107.39(3)degrees). The structure contains centrosymmetric tetranuclear units ([SeCl3](2)[Mo2O2Cl8]) which are analogous to the entities found in the structure of [SCl3][MoOCl4]. The packing of the molecules in beta-[SeCl3][MoOCl4] and [SCl3][MoOCl4] is distinctely different.
