Abstract
Ce4B14O27 was synthesized under conditions of 2.6 GPa and 750 °C in a Walker-type multianvil apparatus. The crystal structure was determined on the basis of single-crystal X-ray diffraction data, collected at room temperature, revealing that Ce4B14O27 is isotypic to La4B14O27. Ce4B14O27 crystallizes monoclinically with four formula units in the space group C2/c (No. 15) and the lattice parameters a = 1117.8(2), b = 640.9(2), c = 2531.7(5) pm, and β = 100.2(1)°. The three-dimensional boron-oxygen framework consists of [BO4]5- tetrahedra and trigonal-planar [BO3]3- groups. The structure contains two crystallographically different cerium ions. Furthermore, Raman spectroscopy was performed on single crystals of Ce4B14O27.
期刊介绍:
ZAAC is an international scientific journal which publishes original papers on new relevant research results from all areas of inorganic chemistry, solid state chemistry, and co-ordination chemistry.
The contributions reflect the latest findings in these research areas and serve the development of new materials, such as super-hard materials, electrical superconductors, or intermetallic compounds. Up-to-date physical methods for the characterization of new chemical compounds and materials are also described.
