The X -ray crystal structure and electronic properties of [Cu(bipy) 2 (ONO)][NO 3 ](bipy = 2,2′-bipyridyl) at 298 and 165 K, a fluxional cis -distorted octahedral CuN 4 O 2 chromophore

The X-ray crystal structures of [Cu(bipy)2(ONO)][NO3] (bipy = 2,2′-bipyridyl) are reported at 298 and 165 K; significant differences occur which are consistent with a fluxional behaviour of the CuN4O2chromophore, and enable the underlying static stereochemistry to be predicted and rationalised using the i.r. spectrum of the nitrito-group and the electronic reflectance spectrum of the CuN4O2chromophore.
