Crystal Structure and Electronic Properties of Y 3AlC3. -Single crystals of Y 3AlC3 are prepared from the elements in a Li metal flux in the ratio Li:Y:Al:C = 36:2:2:3 (Nb ampoule, 1250 C, 7 d; cooling to 600 C with a rate of 2 C/h). The compound reveals a new structure type with the Wyckoff sequence 2j3e and structural features at the border between Zintl and intermetallic phases (space group Pmma, Z = 2, single crystal XRD). The structure comprises 4 different distorted octahedra formed by Y and Al, two of which contain either a central C or a C 2 dumbbell, the others are vacant. The bonding structure of Y3AlC3 is analyzed by electronic structure calculations. -(KOTYRBA, M. R.; CUERVO-REYES, E.; NESPER*, R.; Inorg.

The novel ternary aluminum carbide Y 5 Al 3 C 4 was synthesized using lithium metal as flux at high temperature (1523 K). Singlecrystal structure determination of the title compound revealed a new structure type with the Wyckoff-sequence jhg2da. Y 5 Al 3 C 4 crystallizes in the tetragonal space group P4/mbm (no. 127) with Z = 2 and lattice parameters a = 10.8442(11) and c = 3.5234(4) Å. The compound has metallic appearance and shows remarkable structural features at the
