Figure 2 Crystal packing of Cs3[Lu(dipic)3]·8H2O with hydrogen bonds (in dotted line) and coordinate bonds to caesium. [Lu(dipic)3]3− anions and Cs+ cations are distributed in the cell as successive anionic/cationic layers along the crystallographic c-axis (Lu atoms are in green, Cs in yellow, O in red, C in grey and N in blue). |
