Recrystallization of the solid Cd(10)S(4)(SC(6)H(5))(12) from a solution of pyridine and N, N-di-methylformamide (DMF) results in the formation of the cluster Cd(32)S(14)(SC(6)H(5))(36)-DMF(4) as pale yellow cubes. The structure consists of an 82-atom CdS core that is a roughly spherical piece of the cubic sphalerite lattice approximately 12 angstroms in diameter. The four corners of the lattice are capped by hexagonal wurtzite-like CdS units, which results in an overall tetrahedral cluster approximately 15 angstroms in diameter. This cluster dissolves intact in tetrahydrofuran where its absorption spectrum reveals a sharp peak at 358 nanometers at room temperature and its emission spectra show a strong broad band at 500 nanometers.
从吡啶和 N, N-二甲基甲酰胺 (DMF) 的溶液中重结晶固体 Cd(10)S(4)(SC(6)H(5))(12)，得到淡黄色立方体的簇状 Cd(32)S(14)(SC(6)H(5))(36)-DMF(4)。该结构由一个 82 个原子的 CdS 核心组成，它是一个直径约为 12 埃的立方闪锌矿晶格的大致球形部分。晶格的四个角由六方纤锌矿状的 CdS 单元覆盖，形成一个直径约为 15 埃的四面体簇。该簇在四氢呋喃中完整溶解，其吸收光谱在室温下在 358 纳米处显示出一个尖锐的峰，其发射光谱显示出一个在 500 纳米处的强宽带。
