Step-wise reaction of CdO, Bi2O3, and Cd(NO3)(2)center dot 4H(2)O leads to formation of a novel bismuth oxide nitrate, CdBiO2NO3, which completes the family of bis-muthite-like (MBiO2NO3)-Bi-II oxide nitrates. The new compound is tetragonal, I4/mmm, a = 3.9486(1)angstrom, c = 14.2235(2)angstrom; its crystal structure resembles those of PbBiO2NO3 and CdBiO2NO3, except for, probably, different ...

Step-wise reaction of CdO, Bi2O3, and Cd(NO3)(2)center dot 4H(2)O leads to formation of a novel bismuth oxide nitrate, CdBiO2NO3, which completes the family of bis-muthite-like (MBiO2NO3)-Bi-II oxide nitrates. The new compound is tetragonal, I4/mmm, a = 3.9486(1)angstrom, c = 14.2235(2)angstrom; its crystal structure resembles those of PbBiO2NO3 and CdBiO2NO3, except for, probably, different positioning of the nitrate group. The compound is stable until similar to 425 degrees C when it decomposes, in one step, into CdO and a mixture of Bi-Cd oxides. Cd-based analogs of isostructural PbLnO(2)NO(3 )(Ln - lanthanides) oxide nitrates are unlikely to exist. We discuss the similarities and differences in the structures of layered oxyhalides and oxynitrates of bismuth and rare-earths.
