Solvothermal reaction of La2O3, Sn and Se in dien yields a novel lanthanide selenidostannate [{La(dien)2}4(mu4-Sn2Se9)(mu-Sn2Se6)]infinity, the first example of the coordination of Sn2Se9 and Sn2Se6 ligands to hard Lewis acidic lanthanide metals, while the reaction in en yields an ionic compound [La2(en)8(mu-Se2)]Sn2Se6 containing a ten-coordinated binuclear lanthanum complex [La2(en)8(Se2)]4+ with the diselenide Se(2)(2-) group as a bridging ligand.
水热反应 La2O3、Sn 和 Se 在二烯中生成了一种新型镧硒化锡酸盐 [{La(dien)2}4(mu4-Sn2Se9)(mu-Sn2Se6)]∞，这是首例 Sn2Se9 和 Sn2Se6 配体与硬路易斯酸性镧金属配位的例子，而在 en 中的反应则生成了一种离子化合物 [La2(en)8(mu-Se2)]Sn2Se6，其中含有一个十配位的双核镧配合物 [La2(en)8(Se2)]4+，其中二硒化物 Se(2)(2-) 作为桥联配体。
