Abstract

Three new holmium selenidostannates(iv), [Ho(dap)4]2[Sn2Se6]Cl2 (, dap = diaminopropane), {[Ho(dien)2]2(μ2-OH)2}[Sn2Se6] (, dien = diethylenetriamine), and [Ho2(tepa)2(μ2-OH)2Cl2]2[Sn4Se10]·4H2O (, tepa = tetraethylenepentamine), have been solvothermally synthesized and structurally characterized. consists of two mononuclear [Ho(dap)4](3+) complex cations, one [Sn2Se6](4-) anion built up from two [SnSe4] tetrahedra sharing a common edge, and two Cl(-) ions. consists of one binuclear holmium(iii) complex {[Ho(dien)2]2(μ2-OH)2}(4+) cation and one dimeric [Sn2Se6](4-) anion. is composed of rare binuclear holmium(iii) complex [Ho2(tepa)2(μ2-OH)2Cl2](2+) cations, adamantane-like [Sn4Se10](4-) and free water molecules. Although a few chalcogenidostannates(iv) with lanthanide(iii) complex cations acting as counterions have been reported, their anions are strongly dominated by the dimeric [Sn2Se6](4-) moieties. represents a rare example of an adamantane-like [Sn4Se10](4-) selenidostannate with lanthanide complexes as counterions. The optical properties of have been investigated by UV-vis spectroscopy.
