WebCrystal structure determinations confirmed the presence of one monoanionic carboranylamidinate ligand attached to the metal center in a typical κC, κN-chelating mode. The protonated NHR residue ( 3 : R = Cy; 4 : R = i Pr) is directed away from the metal center and does not contribute to coordinative saturation thereof. WebGermanium (Ge) is the second most popular indirect bandgap (0.66 eV at bulk scale) semiconductor in group IV widely used in microelectronic applications. Generally, Ge nanoparticles are grayish black powder with an average size of 70–120 nm. Usually, Ge is found in diamond crystal structure, which may vary in a cluster of more than 40 atoms.
