Descrição

The crystal structure of 3C13H14N3+FeF63-·3.5H2O was determined. Both phenyl rings of the diphenylguanidine cation are oriented syn to the central C=NH2 group. The anions and cations are held together by a three-dimensional network of hydrogen bonds. In the synthesis of this compound, a second phase (iron trifluoride trihydrate) was formed and identified by powder diffraction data. Mössbauer results show two different iron environments compatible with the two phases reported. http://www.sciencedirect.com/science/article/B6TGD-41C2VKP-B/1/b01b2e4d69d47aa816d3c649782ba41c
