Bis(guanidinium) diaquapentakis(nitrato-[kappa]2O,O')lanthanum

A. Fowkes and W. T. A. Harrison

Abstract: 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.
