Diamondoid Hydrazones and Hydrazides: Sterically Demanding Ligands for Sn/S Cluster Design

A series of new adamantane and diamantane hydrazides was synthesized and coupled with organo-functionalized Sn/S clusters of the general type [R¹Sn₄S₆] (R¹ = CMe₂CH₂C­O­Me) to form diamondoid-decorated Sn/S clusters. The new ligand precursors as well as the resulting hybrid compounds were analyzed by NMR spectroscopy, mass spectrometry, and single-crystal X-ray diffraction, and first insights were gained in the installation of sterically highly demanding and at the same time rigid mono-, di-, and trifunctionalized diamondoid ligands on tetrelchalcogenide cages.
