| Abstract: | A new potassium bismuth phosphate-molybdate K2Bi(PO4)(MoO4) has been synthesized by the flux method and characterized by single-crystal and powder X-ray diffraction, IR spectroscopic studies. The compound crystallizes in the orthorhombic system with the space group Ibca and the cell parameters: a=19.7037(10), b=12.4752(10), c=7.0261(10). This phase exhibits an original layered structure, in which the [Bi(PO4)(MoO4)]∞ layers consist of [Bi2Mo2O18]∞ chains linked through single PO4 tetrahedra. The K+ cations interleaved between these layers exhibit a monocapped distorted cubic coordination. |
