Water-controlled synthesis and single-crystal structural transformations of a cyanide-bridged W(iv)–Ni(ii) molecular wheel complex and 3D networks†
Abstract
One cyanide-bridged W(IV)–Ni(II) wheel-like complex and two three-dimensional (3D) networks can be directly synthesized based on K4[W(CN)8] and [Ni(L)](ClO4)2 precursors by controlling the quantity of water in organic solvent. The water-controlled single-crystal structural transformations among these complexes are described.
