Abstract: | A semi-rigid bipyrazolyl ligand, namely 5-tert-butyl-1,3-bis(3′,5′-diethyl-1H-pyrazol-4′-yl) methylene]benzene, and its Ag(I) and Cu(II) complexes have been prepared and structurally characterized. X-ray
analysis demonstrates that the Ag(I) complex is based on a dinuclear molecular rectangle, while the Cu(II) complex displays
a mono-strand helical structure. Two different conformations, namely cis,cis and cis,trans have been observed for this bipyrazolyl ligand. |
