Cascade complexation of pseudo-halide by dicopper cryptates: a linear Cu–NNN–Cu unit
Abstract
An X-ray crystallographic structure determination of a µ-azido azacryptate has confirmed the existence of collinear Cu–NNN–Cu geometry, earlier cited as the origin of unusual spectroscopy in dicopper µ-azido cryptates; the isoelectronic µ-cyanato cryptate is also isostructural.
