Synthesis and structure of a tetranuclear niobium telluride cuboidal cluster with a central µ4-O ligand
Abstract
High-temperature reaction of NbTe4 with KCN at 450 °C and further crystallization from aqueous solution produces an oxygen-centered tetranuclear niobium cubane-type complex, isolated here as K6[Nb4OTe4(CN)12]·K2CO3·KOH· 8H2O, and characterized by X-ray crystallography.
