摘要：
The crystal structure of Ce4Ru3 was determined by single-crystal diffractometer methods. It is monoclinic, C2/m, a = 8.400(2) angstrom, b = 13.837(4) angstrom, c = 5.985(2) angstrom, beta = 117.90(2)-degrees, Z = 4, Pearson symbol mS28, R = 0.044 for 601 reflections and 36 variable parameters. The structure is characterized by columns of cerium square antiprisms centred by the Ru2 atoms running parallel to the c axis. Pairs of Ru1 atoms are inserted in between the columns. As well as other cerium-rich phases of the Ce-Ru system. Ce4Ru3 shows contracted Ce-Ru distances (2.75 angstrom).
