The First Structure with Isolated Carbon‐Centered Tetrahedra of Rare‐Earth Metals – the New Compound Ce 4 CCl 8

Ce 4 CCl 8 is prepared by heating stoichiometric mixtures of cerium, CeCl 3 and carbon in sealed tantalum capsules at 820 °C. It forms black polyhedral, in fragments transparent orange to red and moisture‐sensitive crystals [space group Pc , a = 13.538(1) Å, b = 10.487(1) Å, c = 22.845(1) Å, β = 126...

Description
Summary:Ce 4 CCl 8 is prepared by heating stoichiometric mixtures of cerium, CeCl 3 and carbon in sealed tantalum capsules at 820 °C. It forms black polyhedral, in fragments transparent orange to red and moisture‐sensitive crystals [space group Pc , a = 13.538(1) Å, b = 10.487(1) Å, c = 22.845(1) Å, β = 126.31(1)°]. The crystal structure contains C‐centered Ce 4 C single tetrahedra, linked by chlorine atoms above edges and corners in different ways. The compound is further characterized by HRTEM, electron‐diffraction investigations and magnetic measurements.
