摘要: Two types of lanthanide selenidostannates(IV) [Ln2(tepa)2(μ-OH)2Sn2Se6] {Ln = Y(Ia), Pr (Ib), Dy (Ic), Er (Id), Tm (Ie); tepa tetraethylenepentamine} and [Ln2(tepa)2(μ2-OH)2Cl2]2[Sn4Se10]·4H2O Y (IIa), (IIb), (IIc), (IId)} have been synthesized under identical solvothermal conditions characterized structurally. Type I (Ia, Ib, Ic, Id Ie) displays 1-D neutral chains [Ln2(tepa)2(μ-OH)2Sn2Se6]n, while type II (IIa, IIb, IIc IId) contains discrete adamantane-like [Sn4Se10]4− ions with binuclear complex [Ln2(tepa)2(μ-OH)2Cl2]2+ as counterions. Although the synthetic methods could result in formation various transition-metal chalcogenidometalates, such experimental usually only stable phases chalcogenidometalates. Hence, two different selenidostannates(IV), obtained same starting materials, first observed this work. The optical properties all compounds investigated by UV-vis spectra.
