[Bi2O2]2+ Layers in Bi2O2(OH)(NO3): Synthesis and Structure Determination. —
The title compound is prepared by hydrothermal reaction of Bi(NO3)3 and KOH (H2O,
180 °C, autoclave, 24 h). Crystal structure refinement from twinned crystals show that
Bi2O2(OH)(NO3) crystallizes in the orthorhombic space group Cmc21. The structure is
based on [Bi2O2]2+ sheets in the a plane. The interlayer space is composed of two slices
containing OH- an N O3 groups, respectively. Within the nitrate layers, the disorder over
two possible N O3 orientations (related by a four fold axis) involves half occupied positions for two of the oxygen atoms. — (HENRY, N.; EVAIN*, M.; DENIARD, P.;
