| Abstract: | Treatment of bis(cyanamide) M(N≡CNEt2)2L4](BPh4)2 and bis(cyanoguanidine) M{N≡CN(H)C(NH2)=NH}2L4](BPh4)2 complexes M = Fe, Ru, Os; L = P(OEt)3] with an excess of amine RNH2 (R = nPr, iPr) affords mixed‐ligand complexes with cyanamide and amine M(NH2R)(N≡CNEt2)L4](BPh4)2 ( 1a – 5a ) and M(NH2R){N≡CN(H)C(NH2)=NH}L4](BPh4)2 ( 1b , 2b ). The complexes were characterized by spectroscopy and X‐ray crystal structure determination of M(NH2iPr)(N≡CNEt2){P(OEt)3}4](BPh4)2 M = Ru ( 3a ), Os ( 5a )]. |
