The Chloride Nitrate PrCl 2 (NO 3 ) · 5 H 2 O with Cationic and Anionic Complexes according to [PrCl 2 (H 2 O) 6 ][PrCl 2 (NO 3 ) 2 (H 2 O) 4 ] Green single crystals of PrCl 2 (NO 3 ) · 5 H 2 O have been obtained from an aqueous solution of PrCl 3 and Pr(NO 3 ) 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 Pr 3+ complexes according to [PrCl 2 (H 2 O) 6 ][PrCl 2 (NO 3 ) 2 (H 2 O) 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.
