Synthesis and crystal structure of the first known Cp* ligated cobalt telluride cluster: Mild oxidation of [Cp*CoCl](2) by Li4Sn2Te6 center dot 8 en to give [(Cp*Co)(4)(mu(3)-Te)(4)]

Oxidation of cobalt(II) complex [Cp*CoCl](2) (Cp* = pentamethylcyclopentadi ene) with binary Zintl polyanion hexatellurodistannate(IV) [Sn2Te6](4-) in Li4Sn2Te, 8 en (en = 1,2-diaminoethane) leads to the formation of the first Cp* ligated cobalt telluride cluster [(CP*Co)(4)(mu (3)-Te)(4)]. The compo und crystallizes as black cuboids that are suitable for X-ray structural an alysis. Space group P1, lattice dimensions at 203 K: a = 1127.9(2), b = 115 6.2(3), c = 1882.3(4) pm. alpha = 83.27(2). beta = 83.24(2), gamma = 66.11( 1)degrees, V = 2222.3(9) 10(6) pm(3) R-1 = 0.0681. The molecular structure of the compound features a Co4Te4 heterocubane and thus distributes to the completion of the series of known transition metal chalcogenide heterocuban es.
