The intermetallic Zintl phase of nominal composition was reported to react with the Te to produce a layered chiral compound with truncated adamantane clusters. The crystal structure of the Te compound was determined from single-crystal X-ray diffraction data collected at 100K on a STOE II X-ray diffractometer. The arrangement of In-Te network if found to create windows of size 0.81 nm within the layers defined by 18-membered rings formed by nine tetrahedral indium sites. The total charge of each window is found to be -3 and is balanced by octahedral, which occupy the middle of each window. The distance between adjacent layers of Te compound is approximately 0.5 Å, which is filled by one-half of each metal complex, the terminal en molecules, and disordered free en molecules. The solid-state UV-vis absorption of a single crystal of Te compound reveal an absorption edge at approximately 2.2 eV, consistent with its orange color.
