Abstract

(Bi2O)Cu(SeO3)3×H2O was synthesized under hydrothermal conditions. The crystal structure was detd. from single-crystal x-ray diffraction data [a 11.012(4), b 16.231(6), c 5.640(2) .ANG.; space group Abm2, Z = 4, R1(F) = 0.0390 for 1430 reflections with Fo>4sigma(Fo) and 84 variable parameters]. The Bi[1+5] atom has one short bond of 2.174(5) .ANG. to an oxo-oxygen atom; the pentagonal-pyramidal coordination figures are edge-connected among each other to form chains. Tetragonal pyramidal Cu[4+1]O5 polyhedra are corner-connected to [CuO3(H2O)] units. Both chains are extended along the c-axis and they are linked by the selenite groups. Probable hydrogen bonds are to oxygen atoms of the selenite group, Ow×××O(23) = 2.604(13) .ANG., O(23)×××Ow×××O(23) = 84.6(6)°. The connection of the Bi atoms and parts of the SeO3 groups show topol. similarities to Bi4Cu3O6(VO4)2.
