The range in static stereochemistry of the cation distortion isomers of the [Cu(chelate)_2Cl]~+ cation, where chelate = bipy, phen or bipyam. The low temperature crystal structure (150 K) of [Cu(bipy)_2Cl][PF_6] centre dot H_2O and [Cu(phen)_2Cl][BPh

摘要

Low temperature crystallography (150 K) has been used to confirm that the two extreme [Cu(chelate)_2Cl][Y] stereochemistries of 3 [Cu(bipy)_2Cl][PF_6] centre dot H_2O, trigonal bipyramidal and 6 [Cu(phen)_2Cl][BPh_4], trigonal bipyramidal distorted square based pyramidal, are genuine and static stereochemistries of the copper(II) ion.
