Figure 19
Influence of the radius of the R element on compounds with identical valence electron amount and constant T element. (a) hexagonal RSi2 compounds and (b) hexagonal R2PdSi3 compounds. The color changes with the atomic number of the R element, according to the color code from the correlation plots. Additionally, the element symbols are given at the top of the diagrams. The markers symbolize lattice parameter a (circle), lattice parameter c (square) and the ratio c/a (hexagon). The standard error is given for the indicated regression lines of the a and the c parameter, separated according light and heavy lanthanides (h and l, respectively). The color code is adapted from the correlation plots. |
