A series of new hybrid selenidostannates [Mn(en)(2)(hda)](2)[Sn2Se6](1, en = ethylenediamine, hda = N-(2-hyd roxyethynethylened lam ine), [Ni (teta)(en)][Ni (teta)(hda)] [Sn4Se10] (2, teta = triethylenetetramine), [Mn(hda)(2)](n)[SnMnSe4](n) (3), [Mn(dien)(2)](n)[SnMnSe4](n) (4, dien = diethylenetriamine), and [Zn-2(en)(2)(mu(4)-SnSe4)](n) (5) were solvothermally synthesized in hda solvent and structurally characterized. 1 is composed of a discrete [Sn2Se6](4-) anion and a complex [Mn(en)(2)(hda)(2+) cation as the counterion. 2 contains the [Ni(teta) (en)](2+) ion, [Ni(teta)(hda)](2+) ion and [Sn4S10](4-) adamantane-like ion built from the corner-sharing connection of four [SnSe4](4-) tetrahedra, which offers the rare example of hybrid selenidostannate combined with two different types of transition metal complexes as counterions. Both 3 and 4 contain a 1-D heterometallic [SnMnSe42-](n) anionic chain constructed from [Sn/MnSe4] tetrahedra sharing opposite edges, whose Sn4+ and Mn2+ ions are situated at the same site in the lattice, but their chains exhibit two different configurations. 5 exhibits a new type of 2-D organic-decorated [Zn-2(en)(2)(mu(4)-SnSe4)](n) layer incorporating rare tetrahedral [ZnSe2(en)] complexes. Their optical and photocurrent response properties were studied, and density functional theory calculations for 5 were also performed.
