Compounds consisting of both cluster cations and cluster anions of the composition [(M 6 X 12 )(EtOH) 6 ][(Mo 6 Cl 8 )Cl 4 X 2 ] ´n EtOH ´m Et 2 O (M = Nb, Ta; X = Cl, Br) have been prepared by the reaction of (M 6 X 12 )X 2 ´6 EtOH with (Mo 6 Cl 8 )Cl 4 . IR data are given for three compounds. The
We have synthesized by solid state chemistry and structurally characterized by single-crystal X-ray di4raction two new cluster compounds based on Nb 6 L i 12 L a 6 units (L ؍ Br and/or F), namely, Nb
The synthesis and the crystal structure of Cs 2 Nb 6 Br 5 F 12 containing octahedral niobium clusters are presented in this work. This bromo6uoride is based on a Nb 6 L i 12 F a 6 (L : Br and F) unit and crystallizes in the orthorhombic system (space group, Cccm; Z : 4; a : 9.2446(2) A s , b : 13.62
