The title compound, (C5H14N2)(2)[La(NO3)(5)(H2O)(2)](NO3)(2), contains a network of doubly protonated homopiperazinium (1,4-diazo-niacyclo-hepta-ne) cations, diaqua-penta-nitrato-lan-thanate(III) dianions and nitrate anions. In the complex anion, the 12 O atoms surround La in a distorted icosa-hedral arrangement. A network of N-HcO and O-HcO hydrogen bonds help to consolidate the crystal packing, resulting in a three-dimensional network. The La atom and one N and one O atom lie on a twofold axis.
