Abstract

Two new molecular metal chalcogenides, tris(ethylenediamine-N,N′)manganese(II) tetratelluride, [Mn(C2H8N2)3]Te4, (I), and bis[tris(ethylenediamine-N,N′)iron(II)] pentaselenodiantimonate(III), [Fe(C2H8N2)3]2(Sb2Se5), (II), containing the isolated molecular building blocks Te42- and Sb2Se54-, have been synthesized by solvothermal reactions in an ethylenediamine solution at 433 K. The anion Te42- in (I) is a zigzag oligometric chain with Te-Te bond lengths in the range 2.709-2.751 angstroms. There is a very short contact [3.329 (1) angstroms] between a pair of neighboring Te42- anions. In (II), each Sb atom is surrounded by three Se atoms to give a tripodal coordination. One of the three independent Se atoms is a μ2-bridging ligand between two Sb atoms; the other two are terminal.
