资源简介：
Three new ‘short’ metallacycles are selectively
obtained
from the reaction of a bimetallic CuI ‘U-shape’
molecular clip with, respectively, the cyano CN–, tricyanomethanide C(CN)3–, and azido
N3– pseudohalogenide ions. These supramolecular
assemblies have been characterized by spectroscopic methods, single-crystal
X-ray diffraction, and elemental analysis. The single-crystal X-ray
structures of these complexes reveal no short contact interaction
between the pseudohalogenide ions within these self-assembled structures
despite the short CuI···CuI distances
within the molecular clips. The formation of these discrete metallacycles
is rationalized by analyzing the structural features of the CuI ‘U-shape’ molecular clip.
