Their crystal structures were also determined. In 1 and 2 only one of the (NO3)- is coordinated to the central atom. The other (NO3)- is away from the metal ion and was replaced by [BF4]- under the conditions of a competitive reaction. The two phenanthroline molecules also occupy nonequivalent positions showing typical π - π interactions in their crystal packing. © 2006 WILEY-VCH Verlag GmbH & Co. KGaA.enArticle
