| Strukturchemische Untersuchungen an Scandium-Cobalt-Phosphiden mit einem Metall:Phosphor-Verhältnis von 2:1  | | | | Abstract
| Several new scandium cobalt phosphides were prepared by reaction of the elemental compo nents in a tin flux. ScCoP has a TiNiSi-type structure with the orthorhombic lattice constants a = 6.268(2) Ä , b = 3.750(1) Ä , c = 7.050(3) Ä. ScCo5P3 is isotypic with YCo5P3. Its orthorhom bic lattice constants are: a = 11.691(5) Ä , b = 3.583(1) A, c = 10.206(3) Ä. Sc2C o12P7crystallizes with the hexagonal Zr2F e12P7 structure with a = 8.973(3) A , c = 3.531(1) Ä. Sc5C o19P12 is of a new type which is closely related to the structure of Hf2Co4P3. It has hexagonal symmetry, space group P 62m —D 3h and the lattice constants a -12.124(7) Ä , c = 3.633(2) Ä , with Z = 1 formula unit per cell. The structure was determined and refined with isotropic thermal parameters from single-crystal counter data to a residual of R = 0.023 for 848 unique structure factors and 24 variable parameters. Considering the environments of the phosphorus atoms the structures are all closely related. There are, however, considerable differences in the coordination polyhedra of the metal atoms. | | | |
