Quaternary Tin(IV) Antimony(III) Sulfide Decorated with Lanthanum(III) Ethylenediamine Complexes: [La(en)₄SbSnS₅]₂·0.5H₂O

A quaternary tin(IV) antimony(III) sulfide decorated by lanthanum(III) ethylenediamine complexes, namely, [La(en)4SbSnS5]2·0.5H2O (1; en = ethylenediamine), has been solvothermally synthesized and structurally, thermally, and optically characterized. Its structure features an isolated hexanuclear molecule of [La(en)4SbSnS5]2. The intermolecule hydrogen-bond interactions result in a three-dimensional supramolecular network, which remains intact upon dehydration.一种由乙二胺合镧(III)配合物（lanthanum(III) ethylenediamine complexes）修饰的四元锡(IV)锑(III)硫化物，化学式为[La(en)₄SbSnS₅]₂·0.5H₂O（编号1；en = 乙二胺(ethylenediamine)），经溶剂热法合成，并完成了结构、热学及光学表征。该化合物的结构以孤立的六核分子[La(en)₄SbSnS₅]₂为特征。分子间氢键相互作用构筑了三维超分子网络，该网络在脱水后仍保持完整。
