The selenidostannates [Mn(dien) 2 ]Sn 3 Se 7 · 0.5H 2 O ( 1 ), [Fe(tatda)]Sn 3 Se 7 ( 2 ), and [Mn(dien) 2 ] 2 Sn 2 Se 6 ( 3 ) (dien = diethylenetriamine, tatda = 3, 6,9, 12‐tetraazatetradecane‐1, 14‐diamine) were prepared under solvothermal conditions. In compounds 1 and 2 , the six Sn 3 Se 4 semi‐cubes are bridged by double μ 2 ‐Se atoms to form the [Sn 3 Se 7 2– ] n lamellar anion containing a elliptical 24‐membered Sn 12 Se 12 ring, which show conformational flexibility of the 2D [Sn 3 Se 7 2– ] n anion influenced by the counter cation. The [Mn(dien) 2 ] 2+ complex ion in 1 is in mer configuration. The [Fe(tatda)] 2+ complex ion possesses similar configuration to the [Mn(dien) 2 ] 2+ ion in 1 . The [Mn(dien) 2 ] 2+ and [Fe(tatda)] 2+ cations are located between the [Sn 3 Se 7 2– ] n layers. Compound 3 consists of dimeric [Sn 2 Se 6 ] 4– anions and octahedral [Mn(dien) 2 ] 2+ complex cations with u‐fac configuration. Compounds 1 – 3 have potential for uses as semiconductors with bandgaps in the range of 1.89–2.34 eV.
