Abstract
A cluster complex of the composition [Zn2(NH3)6(μ-OH)][Zn(NH3)4]0.5[Re4Te4(CN)12]·5H2O is obtained by the interaction of an aqueous solution of K4[Re4Te4(CN)12]·5H2O with an aqueous ammonia solution of ZnCl2. The compound crystallizes in the C2/m (12) monoclinic space group with unit cell parameters a = 23.233(2) Å, b = 14.5906(16) Å, c = 14.3825(15) Å, β = 125.169(1)°, V = 3985.5(7) Å3, Z = 4, dx = 3.290 g/cm3. The structure is built from cluster [Re4Te4(CN)12]4− anions and complex [Zn2(NH3)6(μ-OH)]3+ and [Zn(NH3)4]2+ cations; the latter is disordered over two positions.
