资源简介：
The complex (NHC)AgBr, which bears G1 poly(benzyl ether) dendritic substituents in the NHC ligand, forms a 1D coordination polymer based on unusual zigzag −Ag–halide– chains. The asymmetric distribution of the volume buried by the NHC ligand in the Ag coordination sphere is important to explain the formation of this structure. A Vbur eccentricity parameter has been introduced and used in conjunction with the %Vbur descriptor to analyze the X-ray structures of 100 (NHC)AgX complexes.
