Influence of the radius of the R element on compounds with identical valence electron amount and constant T element. (a) tetragonal RSi2 compounds, (b) hexagonal R2NiSi3 compounds, (c) hexagonal R2RhSi3 compounds and (d) hexagonal R2PtSi3 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 are given for the indicated regression lines of the a and the c parameter, separated according light and heavy lanthanoids (l and h, respectively). The color code is adapted from the correlation plots. |
