摘要

A cluster complex of the composition [Zn_2(NH_3)_6(μ-OH)][Zn(NH~3)~4]~(0.5)[Re_4Te_4(CN)_(12)]?5H_2O is obtained by the interaction of an aqueous solution of K_4[Re_4Te_4(CN)_(12)]?5H_2O with an aqueous ammonia solution of ZnCl_2. The compound crystallizes in the C2/m (12) monoclinic space group with unit cell parameters a = 23.233(2) ?, b = 14.5906(16) ?, c = 14.3825(15) ?, β = 125.169(1)°, V = 3985.5(7) ?~3, Z = 4, d_x = 3.290 g/cm~3. The structure is built from cluster [Re_4Te_4(CN)_(12)]~(4?) anions and complex [Zn_2(NH_3)_6(μ-OH)]~(3+) and [Zn(NH_3)_4]~(2+) cations; the latter is disordered over two positions.
