Bis(1,4,7-triazacyclononane-κ3N)manganese(II) di-μ-diselenido-bis[selenidoarsenate(III)]

“…In contrast to thio-and selenidoantimonates containing trivalent antimony (Sheldrick & Wachhold, 1998;Van Almsick & Sheldrick, 2005a), only a limited number of structural types are known for the corresponding oligo-and polymeric selenidoarsenates (Sheldrick, 2000). In selenidoarsenates(III), AsSe 3 pyramids are typically connected by shared corners or Se-Se bonds into either discrete ring-shaped anions or infinite chains.…”
