ResumoThree new dinulclear complexes containing Cr(III), Ni(II) and μ-CN bridge have been prepared: cis[(en)2FRcNCNi(CN)3]2H2O, obtained by heating trans[CrF(H2O)(en)2][Ni(CN)4] in the solid state and cis[(en)2XCrNCNi(CN)3]2H2O (X = Cl, Br) by treatment with solutions of (NH4)2 [Ni(CN)4]. The new compounds have been characterized by chemical analysis, electronic and infrared spectra and conductivity measurements. The non-precipitation of Ni(CN)2aq with dilute or concentrated acids is noteworthy.
