The coordination chemistry of two symmetric fluorene-based organic ligands with cuprous chloride

Y.-F. Liu, C.-W. Zhao, J.-P. Ma, Q.-K. Liu and Y.-B. Dong

Synopsis: In two complexes, CuI atoms connect the symmetric 2,7-bis­(1H-imidazol-1-yl)-9,9-dimethyl-9H-fluorene and 2,7-bis­(1H-imidazol-1-yl)-9,9-dipropyl-9H-fluorene ligands into one-dimensional chains. In the former, a {[CuICl2]-} unit adheres to the one-dimensional chain through a weak Cu...Cu inter­action, while in the latter, a {[CuI2Cl4]2-} unit links two different chains into a one-dimensional rope-ladder-type chain.

Formula: C21H18N4, [Cu2Cl2(C21H18N4)] and [Cu2Cl2(C25H26N4)]
