| Abstract: | The Chloride Nitrate PrCl2(NO3) · 5 H2O with Cationic and Anionic Complexes according to PrCl2(H2O)6]PrCl2(NO3)2(H2O)4] Green single crystals of PrCl2(NO3) · 5 H2O have been obtained from an aqueous solution of PrCl3 and Pr(NO3)3. The crystal structure monoclinic, P2/c, Z = 4, a = 1228.8(3), b = 648.4(1), c = 1266.0(4) pm, β = 91.91(3)°] contains cationic and anionic Pr3+ complexes according to PrCl2(H2O)6]PrCl2(NO3)2(H2O)4]. Both nitrate groups of the anionic complex act as bidentate chelating ligands. Hydrogen bonds are observed with water molecules as donors and chlorine as well as oxygen atoms as acceptors. |
