文摘

We have established that crystalline nickel-containing metal–organic frameworks (MOFs) bind the complex [Cu(NH₃)₄](ClO₄)₂ from acetonitrile solutions and do not react with [Cu(en)₂](ClO₄)₂. The MOF/copper ammine complex ratio in the products after reaching saturation is determined by the crystal lattice structures of the compounds, and increases from 1.2 (one-dimensional coordination polymer, 1D CP) to 3.2 (2D CP)and 3.9 (ionic MOF) moles of copper ammine complex per formula unit of sorbent. We have shown that it is possible to convert the bound ammine complex to nanosized copper(II) sulfide by treatment with sodium sulfide.
