Abstract

Dinuclear complexes with μ-cyano ligand of formula [(aa)2FCrNCM(CN)3] have been obtained by heating trans-[CrF(H2O)(aa)2][M(CN)4] (aa = ethylenediamine (en); 1,3-propanediamine (tmd); M Ni(II), Pd(II), Pt(II). Chemical analyses, conductivity measurements and electronic and IR spectra justify the formulation proposed. X-Ray diffraction indicates isomorphism for the three mixed complex salts of en, and for the tmd salts. The amine part of the en complexes undergoes a trans → cis change of configuration during the formation reaction; this change is not observed for the tmd complexes. The cis-bis (ethylenediamine) fluoro (tetracyanoplatinate(II)-N) Chromium(III): Cis-[(en)2FCrNCPt(CN)3] shows Pt-Pt interaction both in the solid state and in solution. © 1981.
