Investigations on the transformation of selenidostannates in ionic liquids were extended by using ternary P1-type cluster precursors [M4Sn4Se17]10– [M = Mn (1), Zn (2), Cd (3)], which were synthesized for the first time as their Cs+ salts. Treatment of 1 with 1,2-diaminoethane (en) in [BMIm]­[BF4] yielded two-dimensional-layered [Mn­(en)2.5(en-Me)0.5]­[Sn3Se7] (4; en-Me = H2NC2H4NHCH3). 14 were characterized by single-crystal X-ray diffraction and UV/visible spectroscopy.
