1,4-Diazoniabicyclo[2.2.2]octane tetraaquatetrachlorolanthanate(III) chloride

L. K. Ritchie and W. T. A. Harrison

Abstract: The title compound, (C₆H₁₄N₂)[LaCl₄(H₂O)₄]Cl, is built up from organic cations, [La(H₂O)₄Cl₄]^- complex anions and uncoordinated chloride ions. The previously unseen rare-earth-containing complex ion is irregular in shape. A network of O-HCl and N-HCl hydrogen bonds helps to establish the structure. Prominent among these are two well defined trifurcated N-H(Cl,Cl,Cl) interactions. The La atom, one Cl atom, two N atoms and two C atoms possess site symmetry m.
