摘要

Two different systems were used for syntheses of metal selenides, [Mn(en) _3][In _2Se _5] (1) and [MnSe(en) _(0.5)] (2) by the reactions of In _2Se _3, MnCl _2, and selenium powder at 170 °C for 6 days. Compound 1 contains a one-dimensional [In _2Se _5] ~(2-) chain propagating along the crystallographic c axis separated by [Mn(en) _3] ~(2+) complex cations. The anionic chain is constructed by vertex-linked InSe 4 tetrahedra linked by Se-Se bridges and contains four-membered [In _2Se _2] rings and five-membered [(In ~(3+)) _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.
