Synthesis and characterization of a new cubic structure in the reduced zirconium iodide chemistry

© 2017 The solid-state synthesis and characterization of a new reduced zirconium iodide are reported. Black cubic-like crystals with twinning characteristics and suitable for single crystal X-ray diffraction were obtained when equimolar amounts of Zr, ZrI 4 and MnI 2 were reacted for the nominal composition of Zr 6 MnI 12 . The compound [Zr 6 MnI 12 ] 4 [MnI 4 ] 3 crystallizes in the cubic space group I4¯3d with the lattice parameter a = 23.1879(6) Å. Magnetic susceptibility measurements confirm the presence of Mn in tetrahedral cavities, making it the first compound to have the same element as interstitial and as a cation. This new compound features clusters with two different electronic configurations and with three I a . The structural and electronic features of [Zr 6 MnI 12 ] 4 [MnI 4 ] 3 are unprecedented in the chemistry of reduced zirconium clusters.
