Abstract

Crystals of the new compound LaCo8P5 were prepared by reaction of the elemental components in a tin flux. They have orthorhombic symmetry: a = 10.501(3), b = 3.596(1), c = 9.342(2), V = 352.8 Å3, space group Pmmn, Z = 2. Their structure was determined by direct methods and refined to R = 0.040 for 49 variable parameters and 927 unique F values. It belongs to a large family of structures of which the Fe2P and TiNiSi type structures may be considered as the most simple representatives. Some similarities and differences of the coordination polyhedra in these structures are discussed.
