Solvothermal Synthesis and Structure of the [Ge2Se7]4- Anion in
(enH2)[{Mn(en)2(enH)} 2(µ-en)](Ge2Se7)2 and [Mn(dien) 2]2Ge2Se7. — The structures
of title compounds (IV) (orthorhombic, space group Pbca, Z = 4) and (V) (monoclinic,
P21/c, Z = 4) are determined by single crystal XRD. Both compounds contain the novel
cyclic Ge2 S e47 - anion formed by two GeSe4 tetrahedra. (IV) also contains a novel complex cation in which Mn(II) atoms are coordinated by one terminal, one bridging, and
two chelating ethylene diamine ligands. — (VAN ALMSICK, T.; LOOSE, A.;
