摘要：Two different systems were used for syntheses of metal selenides, [Mn(en)(3)][In2Se5] (1) and [MnSe(en)(0.5)] (2) by the reactions of In2Se3, MnCl2, and selenium powder at 170 degrees C for 6 days. Compound 1 contains a one-dimensional [In2Se5](2-) chain propagating along the crystallographic c axis separated by [Mn(en)(3)](2+) complex cations. The anionic chain is constructed by vertex-linked InSe4 tetrahedra linked by SeSe bridges and contains four-membered [In2Se2] rings and five-membered [(In3+)(2)(Se-2(2-))(Se-2)] rings. Compound 2 has a three-dimensional network containing a monolayer of [MnSe] slabs, which is interconnected by bridging en linkers. The [MnSe] slab is a puckered 6(3) (honeycomb) net formed by alternating three-coordinate manganese and selenium atoms.
