Two
new alkali bismuth oxosulfates, [Bi12O15]Li2(SO4)4 (I) and [Bi7K2O8]K(SO4)4 (II), have been synthesized by heating
a mixture of Bi2O3, CuSO45H2O, and A2CO3 (A = Li, K), and characterized
by single crystal XRD, transmission electron microscopy, and multiphoton
SHG and IR spectroscopy. In the above formula the [BixOy] subunits denote the
3D-porous (I) or 1D-columnar (II) polycationic
host-lattice formed of edge-sharing OBi4 or O(Bi,K)4 oxocenterd tetrahedra. The SO42– groups and alkali ions are arranged into channels in the interstices
leading to original opened crystal structures for these two first
reported alkali oxo-bismuth sulfates. The strong adaptability of the
oxocentered framework is demonstrated by the possibility of preparing
single crystals of [Bi8.73K0.27O8]K1.54(PO4)4 (III) whose crystal structure is similar to those of II with
disorder between OBi4 and O(Bi3,K) tetrahedra
and different channel occupancy due to the aliovalent replacement
of SO42– for PO43–.
