The title compound, (CH6N3)(2)[La(NO3)(5)(H2O)(2)], contains a network of guanidinium cations and the previously unseen diaquapentakis(nitrato)lanthanum dianion, in which 12 O atoms surround La in a distorted icosahedral arrangement. A network of N-H...O and O-H...O hydrogen bonds helps to consolidate the crystal packing, resulting in a three-dimensional network. The La cation, one N atom and one O atom occupy a twofold axis.
