The Rb analogue of grimselite is based on isolated uranyl tricarbonate clusters, [(UO2)(CO3)3], linked through corner sharing to RbO10 and NaO8 polyhedra. The title compound is isostructural with grimselite, with a reduced occupancy of the H2O site (25% versus 50% in grimselite).

The crystal structure of barium pentacyanonitrosylferrate trihydrate, in space group P1, is completely ordered. The study was performed to characterize the structural phase generated by the phase transition undergone by the crystals at 80 K, at which temperature the unit-cell volume doubles. The positional changes of the water molecules with respect to those of the compound at 105 K are presented.

RbCrIII(C2O4)2·2H2O and Cs2Mg(C2O4)2·4H2O represent two novel structure types among double-metal oxalate hydrates. Rb2CuII(C2O4)2·2H2O is isotypic with K2- and (NH4)2CuII(C2O4)2·2H2O. All three compounds have layered structures. The Cr, Mg and Cu atoms are six-, six- and (4 + 2)-coordinated, respectively.
