New representative of Bi95+-containing phases:: synthesis and crystal structure of the NbIV-containing Bi10Nb3Cl18 compound

The Bi10Nb3Cl18 compound was prepared using the high-temperature ampoule method, and its crystal structure was determined by sing-le-crystal X-ray diffraction. This phase contains the Bi-9(5+) cluster polycations and Bi+ cations surrounded by the NbCl62- complex anions. The latter contain the paramagnetic central Nb-IV ions, as evidenced by magnetic measurements.
