Intermolecular interactions in tetrakis(arylisonitrile)-platinum(II) tetracyanoplatinate(II)

Abstract A new reaction allows the preparation of complexes of the general formulae [Pt(CNR) 4 ] [Pt(CN) 4 ] and [Pt(CNR) 2 (CNR′) 2 ] [Pt(CN) 4 ]. The compounds are characterized by their analyses and infrared spectra; their colours range from oranges to dark blue indicating strong interionic interactions. The complexes are soluble in concentrated sulfuric acid and are regained without decomposition by addng water.
